  1. WHAT IS THE TRUE EXPERIMENTAL TWEAK THREAD ALL ABOUT? I have always wanted a thread where any subject is possible. No experiment is too crazy to add here. No idea is too bold to reveal. Take it away! Enlight your thoughts and share your ideas how to improve SQ and how not to. Anyone can encurage and educate you but no one should let you down, deminage you or simply move you to another thread. Everyone is welcome as long as they accepts a different way of thinking! TOPIC DIGEST With a little help of @austinpop I have realised that this thread is all over the place. Even if this is one of the fundamental ideas behind this thread, it could be a good idea to sum-up the things that have proven to be beneficial to SQ in this thread. I will keep it plain & simple. Remember that these are essentially my own findings in my own setup with Tidal FLAC and Tidal MQA as source. As always YMMV! LAN 1. Cat 6a U/UTP 500Mhz ethernet cables sounds better than Cat5, Cat5E, Cat6 & Cat7+ in my setup. Ghent Audio Cat 6a ET02 with JSSG shielding and Metz plugs rules them all. 2. Network switch improve SQ with input on port 1 and output on the last port. Possible explanation is QoS and also that the ports are in different magnetic boxes inside the switch. 3. Using a AQVOX switch with better clock improves SQ compared to a D-Link DSG-105 network switch. 4. A wireless adapter/wireless bridge/router in client mode into a network switch sounds better than battery powered FMCs and hardwired LAN. 5. Router vastly improves SQ with a floating LPS and even more if the floating PSU is connected to a DC blocker trap filter. IME a router upgrade could be beneficial to SQ. 6. Galvanic isolation/DC blocker in the signal path pre the router improves SQ. 7. Wireless adapter vastly improves connected to a floating IT. 8. RJ45 socket enhancers seems to be more efficient on port 4 & 5. Don't ask me why! GND 1. Grounding a metal chassi network switch to a tourmaline grounding box greatly improves SQ. 2. Different tourmaline grounding boxes improves the sound signature in different ways. 3. Grounding the DC negative terminal of the floating SMPS works great. In my setup it sounds best connected to a grounding box instead of to the power strip safety ground receptacle. Just be aware of possible leakage loops between various network devices. A big thanks @JohnSwenson for this tip. USB 1. Covering the outer USB barrels with electrical tape improves SQ slightly with unshielded USB cables. Capasitive coupling between metal barrel and pins? 2. Uptone Audio´s USPCB improves SQ. 3. ATL Hi-Fi´s 8 conductor USB cable with dual unconnected shields (5v+GND & Data- & Data+) with JSSG loop improved SQ compared to other longer (<50cm) USB cables that I´ve tried. DC 1. Network switch sounds best with dual floating PSUs or battery power (but very important to disconnect the battery charger while listening to music). Dual floating PSU is slightly better than battery power, but battery power is slightly better than single floating PSU. 2. Powering several devices with a single floating SMPS sounds better than powering the very same devices with several battery supplies. Also, powering several devices with a single battery supply sounds better than using multiple identical battery supplies. Self-inflicted noise? 3. Canare 4S6 starquad does improve SQ where ever applied. Canare 4S6 with JSSG seems to be even more effective. Thanks [email protected]! 4. Grounding the DC negative output of a floating SMPS improves SQ. Grounding the chassi/case decrease SQ. Be aware of shared ground paths since this could potensially decrease SQ. 5. Dual LT3045 ultra-low noise voltage regulators in series with 1v drop-down close to the powered device improves SQ quite dramaticly. 6. Kemet aluminium Polymer caps A750 series (25v 560uF) vastly improves LT3045 when added at the DC output. On single LT3045 the Kemet improves on both in- and output. 7. Panasonic FC series type A aluminium electrolytic caps improves on the PSU output terminals. AC 1. A DC blocker trap filter pre a safety isolation transformer improves SQ even though it is dead silent (no hum). DC blockers trap filter pre a floating PSU into a router vastly improves SQ. DC stress reliever? 2. SQ improves when battery chargers is connected to a separate powerstrip connected directly to the AC wall outlet, bypassing the isolation transformer completely. 3. A safety isolation transformer with floating secondary improves SQ more than a Ultra Isolation transformer. A balanced isolation transformer with floating center-tap rules them all! 4. Daisy chained floating grounds (dual floating grounds) sounds better than a single floating ground. In my setup floating SMPS's improve SQ connected to a floating IT, even surpassing battery supplies. Thanks for the suggestion @lmitche! 5. AC mains starquad power cables greatly improves SQ. 6. AC mains voltage regulators improves SQ on the signal chain. Even cheaper versions are effective. Not as effective on high power devices such as active speakers and amp due to a still unknown reason.
  2. Hi Everyone, I recently delivery of the SOTM tX-USBultra and posted my impressions on another thread, but here it is again for those interested in this device. Initial impressions of SOTM tX-USBultra: I got delivery of my unit yesterday, then I plugged it in my system in the evening. What I did is to critically listen to 3 or tracks on my system with configuration (1): (1) Nimitra (JS-2)>>Curious 20cm link>>Intona>>Curious 20cm link>>RUR (LPS-1)>>Curious 20cm link>>Brooklyn DAC. The system simply sounded fabulous, music just flows with a sense of realism and 3D especially after installing my two dedicated circuits (one for digital and another for analogue) Here I would like to mention that I upgraded my AO from version 2.0 to 2.10 and it made a significant improvement, then I upgraded to the beta AO 2.20 and the sound went to another level (more transparent, wide soundstage and better separation). Then I removed the RUR+LPS-1 and replaced them with the SOTM tX-USBultra powered by the second rail of the JS-2 at 12V (my unit has the 12v option) so configuration (2) is as follows: (2) Nimitra (JS-2)>>Curious 20cm link>>Intona>>Curious 20cm link>>SOTM tX-USBultra(JS-2)>>Curious 20cm link>>Brooklyn DAC. just out of the box without any burn-in, configuration 2 clearly elevated the sound of my system in all directions, most importantly to me, a sense of feeling that the music is so real and so clear you feel that the notes are sharper and more defined in the soundstage, a veil taken off the music! (a cliche but it accurately describes my experience) I didn't try to power it with the VR MINI because I use it on the Brooklyn and if I change this configuration, then it won't be A/B comparison anymore. My logic now is that I can improve it by freeing the JS-2 from feeding two units and keep it only to Nimitra and get a dedicated PSU to power the SOTM tX-USBultra, but too early now to make any decisions before I get my DC ammeter working. So (RUR+LPS-1) will be staying with me for a short time to do some A/B comparisons after 1 or 2 weeks when the SOTM tX-USBultra has settled in my system and most probably will be listed for sale. My learning is that isolation by ultra-capacitors is important but super clock with a good LPS can be more important. I hope this helps others on a similar path
  3. Hi Everyone, I would like to know in detail about the different implementations of data pathways. I currently use windows and I can hear stark difference between music players with different libraries. Most music players with same library sound similar or identical. HQplayer, Winyl and Xmplay sound identical at identical settings while musicbee is similar but slightly sounds lacking in depth. Aimp sounds very different. Foobar sounds very different and lifeless (apparently goes through windows mixers even in asio and has measurable distortion). Albumplayer sounds very different. I can pretty much narrow it down to - if any uninteded processing is happening (like in foobar), or to the way instructions are laid out. The science of getting jitter free data out of CPU is a topic in itself, and I would like to know if there is any kernel/compiler available for linux/bsd that tries to remove the effect of speculative Execution Jitter. From what I know, the current ways are to have tonnes of Lfence instructions or modify the clang so that the instructions are in such a way that spec/ooo execution or other enhancements always returns a predictable sequence (a miss). I have tried a few such programs and while I can hear differences (with the usb dac and supra cable I have), I am not sure if it is all improvements or if there is any skipping going on. I am planning to upgrade my dac. I am thinking of the dddac but haven't setted on one single dac yet. Without a doubt it will be diy and my intention is to use custom coded upsamplers/dithers that I would pre-processes and store before sending the data in 192khz or 176khz, 24 or 32 bit.. I am now confused on the available ways to transmit the information from the processor to the DAC. I will split up the question into two parts. First question I have is, What are the available protocols that communicate data to the dac? I currently use USB, I can see that the data is fetched, packeted, sent to the USB port dma controller. From here it goes to a USB slave which also has a buffer and converts this stream to timed i2s data which will be fed to the dac. Since USB transfer sequence is timed (i think at 125ms between polls) Isosynchronous mode of USB frame skips frames if 44100hz sample rate is used (8000*5 or 6 alternating missing 100 samples). Asynchronous buffers these things so no interpolation in terms of data transfer but doesn't have any error detection or correction and god knows what type of errors/issues could pop in (I hear changes in cables so I don't believe all is well in USB). I went around looking at other protocols - spdif, toslink etc. SPDIF uses manchester encoding and the slave has to decode clock from the data stream. This kind of makes it necessary to have very good engineering in both the master and the slave, and i'm unsure if they will be that much issue free even after that. And the standard looks variable, general certification is only upto 48khz 24 bit though there are implementations that go till 192khz 24 bit. Toslink does the same with optical format (but not the high quality optical standard used in internet transmission and hence apparently varies with cables). I am unsure if any of these support error detection and/or correction. Also all of these seem to have single serial data line. Is there any dual channel data alternative (Ethernet seems to support dual channel, or is it just full duplex they are meaning?). Another interface I saw was aes which is similar to spdif (or is it a subset of spdif?). Ethernet based audio transfer seems to be what is used in the network streamers, with custom protocols on top of the ethernet protocol if I'm right and it seems to be a good way to go about things before sending to the slave. And direct i2s communication over RJ45 or HDMI seems to be available as well but then again i-i communications are a blank slate meant mainly for inter-ic data pathways and I'm unsure how the protocol will hold up to sending over a large line. I would like to get more enlightenment on this topic and subjective experiences of what works best at the moment, the reliable brands of decoders, reclockers, the available chips, diy-options etc. The second question I have is, how is the data taken out from the CPU/memory. For usb, cpu communicates to the USB controller and fills up the data in its buffer before it sends. Another option I've seen common in single board computers is that i2s is available as an i/o from the board itself. As usual, since a general mass production unit may not have good timing (besides they run out of switching power supplies), there are units that take in this i2s stream, buffer, and regenerate them into i2s,spdif or usb signals (like allo kali,digione etc). I have seldom come across chips that communicate to cpu through PCIe and spit out i2s signals (except maybe pinkfaun). Why is it so. What are the other options available for taking data out from cpu with as minimal jitter as possible (provided the software makes sure the cpu is not introducing a lot of jitter). Are there any dedicated computer architectures meant to handle music streaming well enough (ignoring realtime microcontrollers running dos like operating systems). I'm sorry if it sounded too pedantic. I already have a setup I enjoy even out of usb, and I'm only planning to get a better experience. I just want to learn all the options before diving in. And as an EE student, learning these is a lot of fun, and implementing even more so. This is the reason I'm buying diy dac as well and doing my own custom upsampling, just to learn.
  4. -I don't know where exactly to ask this, but I want this adapter I got (with high hopes...): https://www.ebay.com/itm/USB-Wireless-Bluetooth-3-5mm-AUX-Stereo-Audio-Music-Car-Auto-Adapter-Receiver-US/153739290840?redirect=mobile -And own some Bluetooth headphones I got recently. (Don't think I need to find a link...)Now I like to hook the USB adapter to my TV(the audio out) via an audio cable(it comes with one).(The TV has USB, but I think I really only need the USB power so the adapter has power)Now assuming this hooked up, aren't there like drivers that need to be installed so the USB adapter links to the headphones OR will it just work somehow? I need to hook it all up and see if it works...but what do you guys think?? THANKS!!!!!

  6. I'm using sparky usbridge(dietpi&allo gui system) connected to hydraz, then coax to dac. When playing pcm through squeezelite, everything is fine. But when it goes for dsd native output, dsd stream can not be detected by hydraz and of course no sound can be heard. Then I tried the dac's internal xmos interface. DSD native output goes fine. I guess this indicates incompletely supporting for sparky, right? So can someone help me get hydraz worked for native dsd playing on sparky?
  7. Item is Sold. my mint condition Matrix X-SPDIF 2 DDC for $260 + $12 shipping in the continental US. I have searched high and low for the original white box but can’t locate it. It does come with the included usb cable though. I’m only selling it because my Gustard U16 has a master clock input which I hook my Mutec REF10 to. I will say that it definitely outperformed my modded SU-1 running off a UpTone LPS 1.2, and it sounds great using the LPS 1.2 as a power source.
  8. For Sale My Black Itona Industrial Model USB Isolator with the latest firmware version. $200 shipped in the continental US!
  9. Bricasti M1 > M5 > M12: Network Player - Member REVIEW w/OEM Response from Brian Zolner President/Owner Bricasti below s Hey Guys - I have been going back and forth between what to go with for a Ethernet Network Media Player - either Innuos, SOtM, Sonore, Uptone, Bricasti M1 Network Player or M5, etc. I have a thread dedicated to working toward this decision and got some fantastic help from many CA members. I learned so much and in such a short time. This forum is Fantastic - so many people are so helpful and I appreciate it very much. I am including the link below to anyone interested in that very educational journey. Great stuff if you are interested in Innuos, SOtM, Sonore, Uptone, Bricasti Network Player or M5 I purchased a bunch of these product to try and learn for myself to be sure. I did not want to question my decision with any what if's and wanted the best sounding option for me and my system. I ended up going with the Network Player Option installed in my Bricasti M1SE DAC and I wrote this feedback to one of the best people in all of Hi-End Audio, Brian Zolner President/Owner/Designer Bricasti Design. His digital and analogue products sound absolutely fantastic and the build quality is second to none and the support is as good as it is anywhere. All made by hand right here in good old Massachusetts, USA. I asked Brian if it would be OK if I share my thoughts with the super helpful crew - the CA members that were so important in helping me get to this decision. He said no problem I also asked if he wanted to respond and comment and he provided some great insight below my feedback on his thoughts on the M1, M12, M5 network players and USB audio. I am glad to be able to share this with you guys. I will send Brian this link and I am sure if any of you have any questions or feedback or thought that would be fantastic. We will get you all the info you need. This is some seriously good sounding gear and its a lot less money than the Aurender and Lumin and it blows their doors off! Also, I would love some idea's and feedback and any idea's really now that I am all in with Ethernet audio what is my next step? One member told me to buy The Linear Solution OCXO Audiophile Switch. (link at bottom of the page). This is supposed to provide a great bump in SQ and it is $679 and comes with a dedicated purpose built Linear Power Supply. Please share you thoughts on this or any other upgrade that can help me get the most out of my Bricasti M1SE Ethernet Network Media Player. Subject: Re: Feedback Send to Brian Zolner and Joe at Bricasti Hey Brian and Joe, I wanted to reach out and thank you both for the very kind and outstanding service installing the Bricasti M1SE Ethernet Network Player option in my M1SE DAC. Guys, it is absolutely fantastic! It needed about 40 to 60 hours of burn-in to get to where it was going and honestly the upgrade over that time was substantial. I get that some people don't believe in burn-in and others like me clearly hear it but I am just telling you guys this Bricasti M1SE Ethernet Network Player option is absolutely fantastic. At first I was strongly considering the M5 just because I already own all of the premium - supporting USB Gear and thought it might be great and I am sure it is but honestly guys in all fairness I didn't think the Bricasti M1SE Ethernet Network Player option would end up being this good? Man is it good! I thought it would be good and/or even great but it surpassed even those expectations and that's not an easy thing to do. I am looking for an awful lot out of my gar and I had some premium gear it needed to stand up against. I can speak from first hand experience about this Network Player option and how it compared to all the similar other gear listed below. All my thoughts are in comparison to the gear listed below. I was able to do a/b verse some really good Ethernet / USB options that are some of the hottest, best selling products going and I assumed from an a/b it would be close and/or maybe I couldn't even tell the difference but this is where my non-audiophile wifey serves as a sort of blind test. Yes her ear has evolved but she is not an audiophile. What the Bricasti Network Player option does that is so much better than everything else is actually something you never even knew was missing until you hear it and then remove it. It jumps off the page during A/B's. Sometimes A/B's can be tough but here it stands out as clear as day it was simple. To test myself I asked my wifey for her help and what she thinks. I set up the Sonore/Uptone Combo and then the SOtM/Uptone power supply combo and the Bricasti Network Player and mixed them up and she picked it out each time. She actually picked out the SOtM over Sonore also so maybe her ear is getting better than I think but she heard it and picked it out clearly and simply so that reinforced what I already knew but wanted to check it. Bricasti Network Player is so much more direct and decisive. It's immediacy and directness just can't be missed. I was like "yes, yes, oh man yes"! "Thats what I am talking about" and you know what - those are far and few between these days so when it happens you REALLY appreciate it. Thank you It not like it is a little warmer and a little clearer or it widens or deepens the stage or something like that which by the way it does all these things but that's not my point. It is immediate, decisive and startlingly quick. Its got jump and you are just much closer to the event. It was a combo of heightened transparency with just layers removed and more information magnified and exposed in all its greatness. Also, I want to make sure to note that I am not talking about being more upfront either because it offered a deeper stage and the voices are actually pushed further back which normally I don't prefer. I actually like that dynamic and sort of upfront sound as a rule but that is not what this is. This does it totally different! It does it the only fashioned way. It earns it. This is no designers voicing choice, this is simply a much more robust and substantial component. It performs at a much higher level and it is shows on so many levels. Vastly better separation and delineation in that more direct package. The stage opens and the walls expand and out comes a richer and more layered and more natural presentation. Man that separation is just fantastic! I just can't get over that open space it puts around everything and the air and the extension go on and on. It's just that every item is so sharp and precise and magnified in 3D space. Everything is tighter and wider and deeper and it all just holds together so well and is so confident and that heightened image precision is such an enjoyable effect. I don't want to touch anything - this the best sound I've ever had and I'm ecstatic! Better than analogue IMO. I am sure there are some uber turntables that will out do it but pound for pound I doubt it IMO. I was impressed at this much closer to the event effect. It's kind of hard to articulate but I think this might shed a little more light. Sort of that same effect you get when you have a great DAC or CD player and then you remove the preamp. The only thing with removing a great preamp is you gain that great immediate directness but then lose all that greatness that a great preamps provides but that increased directness is such a desirable effect so many people do it. I did it but then you get a great preamp and you say man I love the directness but I am giving up so much to get it. Some big time trade off's and many go back and forth. I know I did for a while. So this new Network Player upgrade was like keeping your amazing preamp and all the great benefits the pre provides while still getting that great directness a preless set up gives you. Best of both worlds! How often do you get to have your cake and eat it too? Well that is what happened here IMO with this so I think you can see why I am so happy about it and hope this does a little better job of explaining the main effect of this Ethernet Network Player option I added to my system. This preless type directness while keeping all the greatness of a preamp is worth the price of admission all by itself but there is more. All that directness has a great effect on the bass which is tighter, cleaner and more nuanced with much better separation. There isn't any more slam or power. It is not rounder or warmer which some may prefer but it is different. It is more nimble and lighter on its toes with more precision and definition. I don't think its any less powerful but it's different sort of like my Magico speakers are. People think or feel with Magico's sealed Aluminum cabinets there is less bass when in actuality there isn't any less but it is faster and more defined but some interrupt this as less bass but I don't agree but also each to their own. I find it to be a nice improvement and upgrade but I can see someone that likes to listen to a lot pop or rap music they may refer a thicker or rounder sound but everyone else will love this IMO. I will take quality and precision over quantity every time but that's just me and everyone is different. I want take a moment to thank you and your company again for your approach to supporting the folks that purchase your gear. Premium Hi-End Audiophile gear is quite expensive and so many of the top Hi-Fi companies come out with a new model every few years and that kills us. We need to sell our old one to get the new one and that makes expensive gear insanely expensive to own. Many people like me want the most recent and best gear they can afford. You guys make this possible and care more about your customers than any of the other OEM's and we appreciate it very much! You guys are totally different from the Vast Majority of high ends OEM's. Also, this feedback was not made in a vacuum. Here are the items I had in my system that I did an A/B with that allowed me great insight into how your Ethernet Network Player option worked verse the others. Some of these I only owned a for a short while because I knew there was no contest. Most have either been sold or are in process of being sold on Audiogon because your Network Player made them obsolete. I am keeping the JS-2 and P10 for my new system set up. Tellurium Q Black Diamond USB Cable Curious Regenlink USB Cables (2) Uptone Audio USPCB Connectors Uptown Audio ISO Regen USB Uptown Audio LPS-1 UltraCap Power Supply Uptown Audio LPS-1 UltraCap Power Supply Breeze Audio 12v Linear Power Supplies Breeze Audio 12v Linear Power Supplies Uptown Audio Amber Regen USB Uptown Audio JS-2 Linear Power Supply Sonore mircoRendu 2.5 Ethernet / USB Player Ghent customer DC power Cables PS Audio P10 Regenerator SOtM tX-USBultra w/50 ohm connector SOtM sms-200 Ultra w/50 ohm connector I honestly thought in my heart of hearts USB might be the way to go just because it has come so far in not that long of a time. Sonore, SOtM and Uptone Audio in my opinion changed the world in regards to the USB landscape and in a huge way. There are a few others as well. They brought, real world price upgrades to USB that made semi-inexpensive gear better than super expensive legacy products from just a few years back (CD and SACD Players) and this changed the game. Now it appears you have changed the game on the Ethernet side. I call tell anyone out there that doesn't own a Bricasti M1 is to buy the M5. I am not sure how the M5 sounds because I have not heard it but if it sounds anything like the M1 Ethernet Network Player then there is nothing that can touch it. Great job and thank you guys. With your permission I would like to share this personal email on my forum post and if you are ok with it any of your responses as well. People are waiting to hear my thoughts so I thought I could email you and inform them at the same time. Thanks Frank Fsmithjack Subject: Re: Response / Feedback from Brian Zolner Bricasti President/Owner/Designer to Frank Smith / Fsmithjack Frank, Thanks for all that commentary, and well guess only thing I can say or add is once we got the LAN working in the M12, and then the M1 ( it’s the same streamer used in all products) I never went back to USB, clearly better even just connecting with 50’ cat5 from my server to the M1. We do all shows with the LAN and try to convince users this is the way. I feel that regardless of the cables and power supplies and clockers etc for USB that seem to make some differences, one might say they create differences and subjective to if its better or not, but I feel USB is fundamentally flawed and when the player or renderer is installed directly in the M1 it eliminates all the issues of USB, it removes it from the computer, and places it in the M1. We made our own player, running on a linux core on an ARM processor, runs off the linear supply in the M1 too. so no extra processors running as with a PC where the computer is doing all kinds of other co processing, switch mode power regulation on the PC mother board etc. But in the end of all that stuff, this approach eliminates it. For the sound of USB, People are fooled by things and as you point out someone might like the effect of the USB, but I think what we get with the streamer is true sound reproduction with no jitter and noise added to make the sound dance a bit, I hear it clearly on my Tidals, and our M28s, no loss of bass at all for me, but tight clear and excellent extension, no bloating. The M5 was made so that a user could run off the network or PC without using USB, I feel the AES is the best as removes these issues. But installed in the M1 or M12 is the best, direct I2S to the DSP and then to the DAC. The M5 with AES is darn close to what you have, I have done a lot of listening and that was the idea of that product to offer great playback and no USB for anyone and any DAC. Enjoy it, I know it changed my life, my server PC is in another part of the house and I run it all from Jremote, there is just no other way to play, besides the sound there is the convenience factor and I play tracks from my phone or stream from it to the M1, or the server, or the NAS or any PC in my home, all the computer stuff goes in another room away from the listening room. It’s a network and that is what starts becoming interesting and you don’t get that with USB or any other point to point interface. Go ahead and share the story, its what we hope others will find out too. Brian Subject: Re: Response / Feedback from Joe at Bricasti to Frank Smith / Fsmithjack Hi Frank, thank you for great write-up! Enjoy your M1, if you ever need anything just let me know. Thank you again, joe http://www.bricasti.com/en/consumer/m1se.php http://thelinearsolution.com/ocxo_switch.html
  10. Hi to all, I'm Andre with Volumio. I wanted to take the time to introduce myself and the PRIMO. As most of you know, Volumio is the leading media player software used by most audiophiles. Recently, the PRIMO , network music player and streamer , has been released. I am here to answer any questions and start a conversation about what you think of it and eventually even see if any of you would be interested in taking a closer look and share your opinions with the rest of the community. In a nutshell, the PRIMO is: not RPI based its actually Tinkerboard based with the software embedded, so no more SD cards and legendary connectivity issues of the RPI. no more DIY its a finished product in a proper box that takes its place amongst your system plug & play unbox, connect, power on, set up in less than 1 min and play. Volumio is well known for its intuitive user interface and experience. 3 in 1 outputs analog/digital/USB and plenty other features that you can check out here https://volumio.org/primo/ have a look and let me know if you have any questions or comments about it, I'm here to assit with this or any other Volumio related question. Regards Andre
  11. Hi! I got a new USBridge with DietPi, my intention is to use Squeezelite. My DAC is a Soekris 1101 USB DAC. I connect the DAC and power it on. It shows the 44khz - led while it waits for the source to connect. Then I power on USBBridge and wait until it boots up. The result is, that I don't get any sound at all: Squeezelite is "enabled" (which is a sign that somehow it recognizes that a DAC is connected, because without the DAC connected, Squeezelite stays "disabled"). However, Squeezelite refuses to play tracks. Prior to buy the USBridge, I got myself a Raspberry Pi 3 B+ and I installed PiCorePlayer in order to try out the compatibility of my DAC. It worked without problem. Given that I got it to work with a RPi, I thought I could buy a USBridge with no risk. Even more so, as the DAC is natively supportet by Linux according to the manufacturor. Some additional information: The power should not be the problem, as I connect the DAC through a device that cuts the USB power supply from USBridge and adds power from a clean (linear) source. If I connect the DAC directly, it does not power up (I suppose, USBridge does not deliver enough power). This setup works flawlessly with the Raspberry Pi 3 B+ and PiCorePlayer pCP4.1.0. While it boots, the 44khz-led switches off on the DAC. This is not a normal behaviour. Normaly, it remains on normally, or it switches to another value. This might indicate some issue on the communication between DAC und USBridge. Any possible solution??? And: I suppose that PiCorePlayer would not work properly on a USBridge, supporting the clean USB-port? Or would it? If yes, this would possibly resolve the issue for me. And if yes, how to... I am not familiar with eMMC - flashing... If it helps if I provide Log-Files or similar, please let me know how to get them, I am a complete newbie (I manage to SSH into DietPi with putty, but I have no idea where and how to find the log-files). THANKS INDEED in advance! Urs
  12. Hi there, the setup is as follows: Qobuz studio plan Linn Kazoo on iPhone 6s Sonore microrendu in DLNA (settings to Lossless FLAC) USB asynchronous to Naim Dac V1 When playing back 192kHz albums, the highest the chain gets is up to 96 kHz. This is shown on Kazoo and the V1. Can someone help or does someone have an idea? Thanks!!
  13. As USB flash drives with capacities of up to 1TB start to become available, I would like to know if there are any advantages (or disadvantages) in using flash drives instead of solid state and hard disk drives for music replay from locally attached USB storage.
  14. Part 1: iFi Audio iGalvanic3.0 - The Holy Grail of Audio In “The Last Crusade” in a cavern full of cups, Indiana Jones had to choose the Holy Chalice used in the last supper. In USB audio, similar propositions are abound as selecting the best device to improve USB computer audio presents a mind-boggling array of choices. It is widely regarded that one of the most effective USB solutions is galvanic isolation. However, its scarcity reflects the technological hurdles that are not without difficulty. Having spent the best part of two years researching, (hence why we did not bring it out earlier!), we wholeheartedly agree. The iGalvanic3.0 has been one of our more ‘technically challenging’ projects. But the team at iFi Audio are NOW over the moon to announce the iGalvanic3.0. It is one of a kind - able to deliver galvanic isolation on USB3.0 Super Speed. In a sea of USB audio improvement devices, the iGalvanic3.0 really is the ‘holy grail.’ We could have stopped work there and just brought the product to market. Yet, this is not in the AMR/iFi DNA. From this starting point, we invested more time to develop additional features that truly make this product the ultimate solution for USB computer audio. We believe the iGalvanic3.0 will elevate the quality of the audio playback by an order of extreme magnitude. What is the iGalvanic3.0? The iGalavnic3.0 is the one-stop USB audio enhancement solution for every computer audiophile. It offers the USB Trinity of: Audiophile-grade galvanic isolation REclock2/REgenerate2/REbalance2 Clean USB power supply*. *Measured noise is 0.5uV(0.0000005V) @ 500mA load. Outclasses non-iFi USB devices. Bettered only by the micro iUSB3.0. It is a ground-up, dedicated, stand-alone solution that elevates just about every computer audio system. Who benefits from the iGalvanic3.0? Everyone who uses USB for computer audio. More specifically, the iGalvanic3.0 is the ideal solution to: Break ground loops Avoid noise-coupling in applications that require hi-speed USB transfers. Thus, the iGalvanic3.0 is the perfect solution for computer audiophiles through to recording studios seeking maximum sound quality from their USB digital audio system. Stay tuned, next section coming soon! Part #2 High-Tech & High Spec.
  15. Dear Community, I have been reading audio forums for years and should thank everyone for their contributions that have made my listening so good. out of need and desperation I have shown to write my first post. Maybe it will help other users. January I bought a Mutec 3+ USB from Thomann. In my view this device is ice is one of the best I have ever put in the chain and lived up to all the reviews and opinions. Problem is that it is hardly working. I have a Mac mini late 2012 with 10.13 on it as the main digital listening source. The Mutec is sometimes seen by the Midi service most often not. So I have tried a lot of fault finding: Two other macs USB 2 vs 3 USB c Cables Power Different OS (Mojave vs Sierra) boot sequence factory resets For some reason the Mutec disappears of the midi and will not come back with any certainty. Then after all the methodical switching it will just pop up if I move the USB to a machine or port that did not work minutes before. I had a long dialogue with Chris at Mutec (CEO) and they could not help. This device sounds so great I do not want to scrap it. Has anyone solved this problem before. I have Audirvana, ITunes, Pure Music etc but the problem seems to be at the Midi, before the applications. chain = Mac > Mutec > minidsp 4x10> 4x power amps > 4 way speakers the Mutec locks on (blue light), sometimes does not get the right bit rate, sometimes does. Your wisdom and experience gratefully received Eddiechilli
  16. iDEFENDER3.0 The iDEFENDER3.0 solves the common ground loop/hum. It ‘breaks’ the ground loop but in a, proper and electrically safe way Just add iPOWER 5v to inject clean power at the source. Break ground loops the correct way. iDefender3.0 with IsoEarth® Use upstream at the audio source. Because USB is bi-directional. Latest USB3.0 standard. For optimum performance. Cut-off noisy power. Inject pure, clean iPOWER 5v. The iDefender3.0 protects against the common problems of ground loop noise and noisy USB power (if used with optional external iPower 5V). As USB is bi-directional, it is important to address noise issues upstream as well as downstream. Common USB noise problems addressed by the iDefender are: [*=center]Breaks noisy ground-loops. Significantly reduces system noise floor and makes for better dynamic contrast, warmth and resolution [*=center]Disconnects the USB Power from the PC and replaces it with a clean external power (optional iPower* 5V for ultra low noise) [*=center]USB3.0 port technology – most advanced and highest USB specification The iDefender, just like its iUSB power sibling, brings usb port noise at the computer from a typical 100uV down to 1uV. So a 100x reduction that is quieter than a 9v battery. Beneath the compact exterior, the iDefender is feature-rich, with the latest iFi technology. To be used directly at the Source such as the PC usb port, it breaks ground loops and cuts the noisy USB power line. From computer audiophiles, musicians, home studio artists to pro audio customers, it improves audio playback quality at home and on-the-go. *To obtain the best result, the optional iPower 5V is recommended. USB is bi-directional, pays to look upstream Unlike SPDIF which is directional, even as the USB logo itself illustrates, USB is bi-directional. Therefore, despite more efforts and benefits to looking downstream such as at the DAC end, we believe it is also beneficial to look upstream at the source. The iDefender3.0 solves one quite common issue found with either: 1. Multiple earths 2. No earth That is a ground loop which manifests itself as an audible ‘hum.’ The iDefender3.0 cuts the ground loop AND also offers the ability to inject a clean 5v power supply via the micro USB port at the side. For computer audio enthusiasts to professional recording studio engineers, the iDefender3.0 slves these two issues in one fell swoop. Break the noisy USB power, but in the correct way There are more than a few products that break the USB Power connection, but of the ones known to us, they do very little because the noisy ground connection remains. This is quite a major oversight in our opinion. For DAC's that do not use USB Power (except for handshake) the iDefender3.0 breaks the ground connection eliminating earth loops, while allowing normal handshake operation to continue. So in terms of cutting out the noise, it does it in the most comprehensive way possible while at the same time, in an electrically correct way. USB3.0 technology, at the cutting-edge It is now a hallmark of all the latest iFi signal and power products to be USB3.0 standard. First USB3.0 is backwards compatible with USB2.0. Second, in terms of the specifications, USB3.0 is superior to USB2.0 eg the wire gauge specification is more exhaustive and the connections are better. Need clean power? Inject iPower ‘quieter than battery’ technology As the iDefender3.0 breaks the noisy power supply, this is it for DACs with an internally-powered USB line. But for DAC's that use USB Power a separate power connection is provided to feed in a 5V DC Supply - this is needed to break the ground connection, as long as the DAC tries to draw USB power from the Source instead the ground cannot be isolated. With a noise floor that of 1uV, the iPower is a new-breed of near silent DC-power supply. Low power consumption and low-noise. With 12-Element Array on the output and 6-Element Array technology on the input, there is next to no noise supplied and ‘leaked’ back out to nearby devices. Specifications: Super-Speed USB3.0 (and USB2.0 backwards compatible) Connectors: USB3.0 gold-plated connectors Dimensions: 48 (l) x 18 (w) x 8 mm (h) Weight: 6.5g (0.23oz) Warranty period: 12 months The EU retail price: €49 incl VAT The US retail price: $45 ex-tax

  18. Hello everyone, For the past year I have been experiencing issues with macOS USB Audio implementation. Ocassionally, when using a USB DAC (in this case a Wadia di122) if there is a track change and the sampling rate is different to the previous track or idle state, there is a sudden burst of distorted audio and white noise coming out of the speakers. It sounds very similar to when one does process little--endian data as if it were big-endian data. You somehow hear the music behind that big mask of white static noise. I have to say this does not happen every time the sampling rate switches from one frequency to another but it does happen and when it happens it always follows the same pattern. Originally I thought it was the DAC, so I spoke to the dealer and I was offered a brand new replacement, which I gladly accepted. After a few days the issue appeared again, so I decided to look further into it. Whenever this happens, the DAC shows the correct sampling rate, the music software (roon, audirvana and hqplayer) they all show the right track info, and appear to be playing the track correctly. There are no messages in console and not a single error or warning anywhere in OS. I contacted Wadia (McInstosh Labs) and they pretty much didn’t know what to tell me. They suggested replacing the USB cable (something I had already tried), unplugging all other equipment (tried that too) and as a last resort, up sample everything to 192K or 384k (which didn't work). I have tried many things, reinstalling different macOS versions from El Capitan to Mojave, disk repairs, SMC and NVRAM resets but the issue will eventually occur at some point again. I even tried it on both, my Mac mini 2012 and my MacBook Pro 2015 (Plugged and battery only) and the same thing happened. Then I decided to go the Windows 10 route and I was surprised after weeks of intensive testing no loud bursts of noise were to be heard, (using the Wadia drivers for Windows). I then installed Linux on that old windows laptop and the DAC has had no problems with it for the past month. In the meantime I had also tried with a couple of DACs. An old Arcam rDAC I had lying around had not problems at all but I guess it is due to the fact that it works under the USB 1 protocol. I also had the chance to try with a Rega DAC-R (revised versión) and it did not show the loud white noise issue) but macOS had trouble recognising it under midi settings, had restart and reset SMC so that it would appear listed as a connected audio device. On some internet searches I did, I noticed that there are quite a few USB Audio-related entries about people having sporadic and sometimes weird issues for which there are no proper resolutions yet. Perhaps, in my case, the issue could be solved by having Wadia look at the firmware and see if there is something that needs to be revised in order to make this wonderful sounding DAC more compatible with macOS. I just doubt there is anybody at McIntosh Labs interested in looking into it. Same goes for Apple. I’ve used Apple products for more than a decade and there is certainly a change in the way their products are presented.They are still very functional in many aspects but very mainstreamed in the sense that they might no longer cater for the audiophile end corner of the market. If anybody has had similar experiences with macOS USB audio implementation, please post. Audirvana - Wadia di122 noise.m4a
  19. I have recently returned to using USB after acquiring a Teac UD-501 and I am curious about what people are using to improve the performance of the connection. I understand that there is a lot of speculation about this, that little if any measurements have been provided supporting the effects of these gadgets and tweaks but still I think it would be interesting to know how many people believe that they have improved performance by adding one or more of these gadgets. It would also be interesting to learn about which DACs are less susceptible to USB "interference", meaning that the effects of the aforementioned gadgets are unnoticeable or marginal at best. Feel free to suggest more/new choices as I am not familiar with everything that's being sold as a USB remedy.
  20. I am doing preliminary planning for a dedicated audio computer to replace my modified laptop. My W4S DAC accepts I2S input. From postings here I2S sound quality is at least as good as USB and probably better. Pink Faun and maybe others make an I2S out board. So I am thinking of using I2S and maybe building in a good USB output to make direct comparisons. Anyone have experience using I2S out and into their DAC, comments on SQ, tech issues, etc. Thanks.
  21. A Guide on how to get the most from your Schiit Eitr I recently began a quest to determine if it was possible to improve sound from the Schiit Eitr. There are three variables I knew to explore: USB Cable from source to the Eitr S/PDIF Cable from the Eitr to the DAC Power Supply (not necessary: LPS already used by Schiit) Where I am coming from: I listen using HD800S phones powered by a Kenzie tube amp and Brooklyn DAC+. I avoid powered USB hubs and connect the Eitr directly from a USB 2.0 port on my Win 7 Pro laptop. USB Cables Do Make A Difference My first experiment involved comparing the popular Blue Jeans USB 2 cable to the AudioQuest Diamond USB Cable, Type A to Type B, 0.75m. AudioQuest Diamond USB Cable Review Source was Tidal HiFi using non MQA tracks I was very familiar with. After listening using the Blue Jeans cable I swapped in the AudioQuest Diamond. The most immediate difference was in musicality: tracks were more enjoyable to listen to. Consider swapping a basic turntable for an LP-12 and the music becomes more "tuneful" as Linn used to say. To be more specific sound stage became wider, deeper and taller using the Diamond cable. There was more air around instruments and voices. Treble was silky smooth and I noticed more impact in bass. I heard more detail and it was easier to listen deep into the tracks. Advice: if you have a very revealing system and can get an AudioQuest Diamond on trial from a dealer try it for yourself. Bits are not always just bits and USB cables do make a difference. I have an interesting high-end S/PDIF cable on the way and will update once I have a listen.
  22. Has someone compared SQ of direct USB output from MBP/Audirvana to DAC vs. streaming to a device like Ultrarendu or USBridge with the same DAC and same USB cable ? Thanks Matt
  23. Hello, I have been using usbridge for almost a year with my Auralic Polaris (usb-dac) and Squeezelite. I control my system with iPeng. Dietpi v6.6 was installed in the headless version. After the update to 6.8, there was an issue. Usbridge has no sound output. I reinstalled Dietpi with allo gui (version 6.6). Sound was back. After an update to 6.8 again no sound output. Does anyone know this behavior? What could be the reason? Thank you
  24. Observations In his article “Computer Audiophile Turns 10 Today” Chris Connaker, the founder of Computer Audiophile, noted of Apple USB ports: "April 11, 2008 - A USB Port is Not a USB Port - So, what is the deal? Apple's design of the USB architecture in MacBook/Pro models is flawed in my opinion." We have recently witnessed the rise of an understanding of the need to clean up the signal when feeding DACs via USB from computers: this forum is filled with solutions. From my experience, using an Audioquest Jitterbug into various DACS (when fed from my MacBookPro via USB) has, on all occasions, noticeably improved the sound. Questions So I am wondering: - In relation to USB output, are some Apple machines “cleaner” than other Apple Machines? (So, for example, does a MacMini provide a cleaner USB output than a MacBook Pro?) - For machines that have more than one USB output: I know I am able to access information on the USB ports from About This Mac/ System Report. But once accessed how would I determine which port is "cleaner"? - Have any of you hardcore Mac Heads done any comparisons on the USB outputs of your Macs? Or compared Macs?
