About Me

  1. [EDIT: The original first post of this long thread had outdated information and so is deleted.] Development of EtherREGEN is complete. The web page for it is up (UpTone Audio EtherREGEN), and a new thread for the launch has been started. Please see:
  2. I have an innuos SE which I've had since new (about two and a half years) and I was just wondering what forum members would recommend as the minimum requirement for Ethernet use and treatment for streaming. I've predominantly used it as a server playing music directly from the SSD up until now. My current set up is literally a plain common or garden mains powered Technicolour TG589 V2 Ethernet switch plugged into a mains powered TP Link Powerline then in a separate room I have another mains powered TP Link Powerline and then an Ethernet cable that goes from that straight into my Innuos Zenith SE. So about as wrong and as basic as you could get I suppose. Any and all recommendations, suggestions and help are welcome.
  3. 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.
  4. The DAC501 is Weiss Engineering's new state of the art D/A Converter with an unprecedented level of sophistication and versatility. With the DAC501 Weiss is creating a new paradigm for what used to be a black box device. A typical D/A Converter is a "set and forget" device. Not so with the DAC501. It adds a number of interesting signal processing features and sports a variety of digital inputs. Balanced, unbalanced and headphone outputs are provided. Weiss Engineering has a 30 year history in D/A Converter design. In that time span they have learned a thing or two about converter design. The DAC501 is the essence of their experiences. FEATURES Inputs AES/EBU or S/PDIF via XLR, Toslink and RCA UPnP / DLNA (via Ethernet) USB Accepted formats: PCM 44.1kHz up to 384 kHz, DSD 64x / 128x Future formats can be accommodated for via software updates Outputs Line out unbalanced on RCA connector Line out balanced on XLR connector Headphone out on 1/4" Jack Analogue One of the latest 32 bit D/A Converter chips is used Discrete output stages for both line and headphone outputs Signal Processing The DSP algorithms can be different depending on which output is selected (line or headphone). Some DSP algorithms have to work differently if they are used for headphones in comparison to speakers. Creative Equalizer - A tone control with low boost/cut, high boost/cut and mid boost/cut. Very useful to correct those recordings which do not quite fit your taste. De-Essing - The automatic removal of overly bright sibilances from human voices. The sibilance effect can be more or less pronounced depending on your speakers or room acoustics. Constant Volume - Adjusts the audio volume (loudness) to a constant value across all tracks played. Useful for "party mode" when the volume control should stay untouched. Vinyl Emulation - Get that special sonic character of a record player based playback chain. Crosstalk Cancelling (XTC) - For the playback of dummy head recordings or live recordings via speakers for an incredible live sensation. (For speaker based playback only.) Out Of Head Localization algorithm - Tries to get the music "out of your head" when listening via headphones. The goal is to achieve a similar listening sensation as one gets when listening via speakers. (For headphone based playback only.) The DAC501 is operated via the rotary encoder control on the faceplate, the touch sensitive color LCD display or the IR remote control. Some additional settings can be done via a web interface from any computer. Controls The DAC501 is operated via the rotary encoder control on the faceplate, the touch sensitive color LCD display or the IR remote control. Some additional settings can be done via a web interface from any computer. Mechanics The DAC501 has a similar size as the Weiss DAC202 unit. The DAC502 version is a larger size unit, similar to their MAN301 unit. The features of the DAC502 are the same as the ones of the DAC501. We've now begun accepting pre-orders.

  5. I bought a microrendu 2 days ago and I feel I have to get a lot of accessories to make a "simple" system "complicated". The reason to choose microrendu is due to its simply design. Now I have to play with router / NAS / Music Servers / Extensions and worry about degrade of sound quality. My original plan is Sotm SMS1000Q WE (or any other optimized PC, like CAD, Mojo etc). For more details about an optimized PC : any PC with low power assumption (generate less noise), separated power supply to USB, low noise circuit design, internal power filter and linear power supply ,EMI isolation, low jitter clock etc. Any kind of optimized PC can feed signal to USB DAC with highest bit rate support via STABLE PHYSICAL connection. [PC - USB DAC + linear power supply]. How about Microrendu? I was attracted by the CA reviews and bought it. Now I realize the system is not simple at all and the system may have inferior SQ due to ethernet transport parameters, plus, the routers and photoelectric conversion modules of those systems are not audiophile grade. [Music Server / Router / Microrendu / USB DAC / Several linear power supply / Maybe Ethernet Switch / NAS]. How could I convince myself to invest further in microrendu system because I could not see any advantage now. How about SOUND QUALITY? Thanks for any suggestions.
  6. Mint, as new, AQ Vodka Ethernet cable. 2.5 feet. Original box and end clips. $185 I did comparisons with Supra, Blue Jean, and stock cable and this far exceeded all of them regarding clarity, PRAT, and richness. Selling because I bought an Antipodes DX3 to replace an SOTM sms-200 and SonicTransporter, and now only require 1 Ethernet cable.
  7. In examining the benefits or disadvantages of replacing USB wiring with Ethernet wiring for transmission of audio data, there's a question on the type of NIC used for the Ethernet interface. Uncovering the typical transformer design, the class TI NIC chips use a combo of centre tapped transformers. If these are a transformer in the classic sense, there's still capacitance across the windings, so wouldn't any high impedance leakage currents be transferred through the wire? There are transformerless NICs that use caps instead, the TI notes limit the transmissions to 100Mbps which would be OK for audio, but looking at the Newegg site for Intel Nics, there are photos which don't show larger inductors, or components starting with L or H for example. There are NICs which work at the 1GB speed, but just wonder what sort of waveform that ends up to be. The transformerless designs use a set of capacitors, which effectively block DC and have a high immunity to spike voltage. Apart from cost would the transformer provide a more difficult opposition to high frequency impedance leakage currents than the caps design?
  8. I have a DigiOne player with Volumio. I've had it for about 2 weeks. It is connected to my router with an ethernet cable. I am using Audirvana+ for Windows to send audio to it. I shutdown my laptop every evening. The past 2 mornings, the player has disappeared from Audirvana's option for output. I had to reboot the DigiOne player (once yesterday, multiple times today) in order to get it to reappear. I still can't reach the Volumio interface through volumio.local (this worked when I first connected it to my network). Why does it keep disappearing? I love the player, but this will get old fast if I have to keep rebooting it.
  9. Hello, I just received my USBridge. It connects to the network fine using the onboard ethernet. When I try to use the gigabyte dongle purchased from ALLO, it fails to power up from any of the sparky ports. I tried it on my PC and it powers up just fine. Please advise.
  10. After doing forum research, I decided it was possible to stream Roon from my Mac to the Roon-Tested 280D. Now I'm looking for you experts to confirm/deny before I install the over $1600 of gear purchased to make this happen! Set-up - my Mac, now with Roon downloaded, is quite some distance from the Moon 280D and the listening room where its housed. So it is impractical or impossible to directly connect a USB cable from it to the 280D. Plan - I purchased the ultraRendu microcomputer to work as a go-between. It will be directly connected to my router. As I understand things, it would recognize Roon and pass it thru via USB to the Roon-tested Moon. Concern - Simaudio is only pushing a direct computer connection, which is what they evaluated in order to become Roon Tested. I'm sure Simaudio has not tested the ultraRendu or all the many other similar products to determine their usability with Roon Hope - In spite of that, I'm hoping the envisioned solution is a workaround that's been tried and tested by others, whether the ultra/microRendu was used as the Roon end point or not. Thank you in advance for you help.
  11. I've run into a new problem and didn't know if anyone had any similar experiences/solutions. Thanks in advance. I am currently using a microRendu in an area of my house that does not have (and cannot easily get) wired ethernet. I tried using it plugged into an eero base, but had some drop outs. I have been using TP-LINK AV2000 Powerline Adapter with good results. I changed up my system and with my new Wells Audio Milo I am picking up noise from the power line adapter. If I move the adapter to a different outlet than my amp is plugged in, it improves. I still have audible interference (sounds like data transmission to me) but it is better than when both are plugged into the same outlet. I have had some improvement adding a better/shielded power cable (Cardas Clear M). It's better but it is still there. If I turn off the DAC (Schiit Gugnir Multibit), the sound is still there in the background--so I think it is from the amp itself. Any suggestions? I'm looking into hardwiring the ethernet, but this will be expensive and require drywall work. I've considered the Auralic Aries, but like my microRendu. Thanks for any suggestions. Mark
  12. I have today discovered that I could update my Weiss Minerva dac by having a Ethernet interface installed. That will turn it into a renderer. This has been available since 2015 and I am ashamed to admit that I have only discovered it today. The same product is also available for some of their other products. Has anyone here done the upgrade? If so any views?
  13. Guys, I'm about to have new flooring put in and would appreciate guidance on cabling to future proof the family's media/music consumption as much as possible. Needs -We want to remove any WiFi use. -Listening room is currently the TV Room (including modem) which will continue -Want to listen to music in front room (may relocate Turntable there) -Kids will want to listen to music in their bedrooms soon -Would also like to have wired Security cameras around house. Current set-up in TV/Listening room -Gigabit Internet with Comcast, Netgear CM1000 (Docsis 3.1), Synology Router RT2600ac, Synology NAS, Ultrarendu>W4S Dac-2>Mcintosh C46 Preamp>Job 225 amp>Salk Song Tower Speakers Specific Questions: -Any recommendations on Ethernet cable to future proof? -Would XLR cabling from the Mcintosh degrade if it was around 36ft -Any other equipment recommendations/tips based on your experience? Thanks in advance.
  14. Hi; this is my first post (after the loosin' Bio data from... that time...) (Sorry for my English and... thanks to all of you) Well, after many digital sys over PC, I -finally- found the sound I like, with no differences (and if there are, they are better listenings than... CDs) from any other digital front end, I mean my transport/DAC Simaudio Moon 750D. My goal was to put away PC from the audio chain, so... NAS (QNAP TS251 fanless)... router (Fritzbox)... renderer (MiND 180 by Moon, Simaudio) and through AES/EBU_XLR 110-Ohm cable (Apogee Wide Eye) to DAC. All cabled with Ethernet CAT 6a shielded. Because "the game" to improve the sound but without spend (so much) money on other gears, even changing "the tonal balance", I was surprised when I add the "linear power supply" to router/NAS/renderer. Very good for my ears! But... "more": I want "more"! Waiting for MQA (Moon website writes... 1st quarter '18), I wrote to "iFi audio" to know if there are in their big catalogue some "good stuff", some "iSilencers" and so on: they gently said to me that over Ethernet there is nothig so significant at the moment because Ethernet is a very good place to stream direct to DAC! I also read this very interesting article about, on SoS: https://www.soundonsound.com/techniques/ethernet-audio So, my "QUESTION", without talking about PC's and USB's, is: what do you say about? Is there only a chance to change devices to improve the sound over Ethernet? And... What about the UPnP AV music server??? I use the "MinimServer" and it flows very good, but I heard about Roon Sever just few days ago: is this a better choice? The only way? Any advices for me? (Are you informed for something like Roon Server competitor? Free?) Thanks and sorry for the long post: I will read you. Bye, Luca from old EU
  15. A recent video posted by WireWorlds David Salz blatantly shows they don't know what they are talking about:
  16. I know that nobody really knows, but do you have any guesses? I'm assuming they will soon be on their way out, given the direction the newest retina MBPs are taking. My MBP is just under three years old, but I'm tempted to grab a new 13" non-retina MBP (the only one left with an internal disc drive) while they're still around. (Reasons if you're interested: They are cheaper; I don't like extra hardware cluttering my desk, i.e., an external drive; I like having an Ethernet port, which the retina versions do not have.) THANKS. -Bob
  17. Is anyone using a solution whereby the music source output ( computer, NAS, renderer, etc.) is going into a DAC via an ethernet connection? Cheers
  18. My digitial audio server (iMac) resides in one of the bedrooms (office) in my house and of course, the audio system is elsewhere (living room). I having been trying to graduate from using Airport Express for this connection to benefit (or at least determine if there is a benefit) from higher def music files. My first attempt has been with an AudioEngine D2 wireless system to connect with BitPerfect on the source end. Although I've followed their guidelines on placement of the transmitter (away from other 802.11 wireless devices, setting the 802.11 network to channel 1 or 11, etc.), I still get sporadic cut-outs. Sometimes it makes the music unlistenable and other times I may get a single cut-out during hours of listening. There is also some weird noise that I can't really quite hear, but seems to come and go, that is never present when playing material directly on the audio system, such as from a CD or LP. This may simply be a lower impact result of a bad connection that doesn't occur as a cut-out. While the folks at AudioEngine have attempted to help, I'm not confident that wireless is the way to go. I found another product made by Vanco that converts digital audio (coax or TOSLINK) to something that is are transmitted over ethernet and then converts back to usable digital audio at the other end. It's very inexpensive (~$100), but I'm thinking I may end up with a different set of problems than I've already got, but more subtle and difficult to resolve. Does anyone have experience with such a device? On paper, it seems like a really good idea as it supports up to 96kHz bit rate. I'm just a little suspicious that something this inexpensive has some downside I haven't thought of. Thanks Jim If you want to see my audio system, it's posted here.
  19. Hi, I'm currently using iPad to transfer music data to a Musical Fidelity v90 DAC via "lightning to USB camera kit" & "Atlas Element USB AB cable". Now I'm planning to put all my music data to NAS, may I ask will it the same to transfer data to the DAC via Ethernet cable? Or it's actually different? Thanks all : )
  20. Apologies in advance for a naive question, probably answered somewhere on the site, tho I can't find it. I am using Mac Mini running J River Media Centre in one room then wifi to an Airport Express in another, connecting to my amp via a 3.5mm jack and cable. There is a solid concrete floor between, so the wifi connection is not great - annoying dropouts. Connecting the two parts of the system by wire would be difficult - the concrete floor again. I am looking at Ethernet over Powerline. Can someone please outline the connections? I realize the signal over the powerline is digital, so I need a DAC between the powerline adapter and the amp. Is it as simple as Mac Mini to router, router to powerline adapter1 by ethernet, adapter2 to DAC, DAC to amp? Any other suggestions?
  21. Hi, Has anyone tried using one of the USB to Ethernet adapters. The reason I ask, is I'd like to place my DAC near my preamp and amps. But I want my computer close to me so I can fiddle with settings, restart it, tag files etc. it would take about a 20 foot USB cable to do this and I know that's bad. I would need two of these, one to convert USB 3.0 out to Ethernet and another from Ethernet back to USB. I'd also need an USB 3.0 female to female adapter to attach my Lampizator USB cable to, and then into the USB port on my DAC. It seems like a good solution but I do worry about SQ. Below are the links to a couple of these items on Amazon.

  22. Hello. I am confused about what is the best means (sound quality wise) of moving digital music files to a DAC. I read all about USB DACs using asynchronous connections so that the DAC takes over clock duties from the Pc (is that something to do with jitter?), how the various types of connections can be limited in the music file's maximum bit depth and sampling frequency etc etc. How does ethernet fare up sound quality wise? I assume it is unlimited when it comes to the music file's bit depth and sampling frequency, but what about jitter, clock ownership? Please, can someone out there tell me what the best connection is, technically? I am assuming that the best connection technically will also be the best connection for outright sound quality?? Many thanks.
  23. I am looking into a Bryston/Marantz/CAPS/Aurender type media server. Is there a difference in sound quality having Cat-5 Ethernet directly from NAS or router to media server versus say setting airport express in the listening room and running CAT-5 out of it into the media server? My problem is that we have an old house, and large distance between room where the router/modem is and the main listening room, and hardwiring everything will cost some $$$. Present Setup: a Synology NAS upstairs in an office hardwired via CAT-5 to an Apple Time Capsule. The Time capsule, however, is NOT hardwired to the Router (downstairs), but runs off WiFi. My listening room is also on the main floor (with the router/modem), 125 feet from the main router (and downstairs and 100 feet from my NAS) I can hire someone to hardwire CAT-5 from the NAS to the listening room or router to listening room,but not sure that is worth it as the NAS is essentially already wirelessly connected? I assume, if there truly is a benefit to hardwiring it, that I would also need to run CAT-5 from the 1st Floor modem/router to the 2nd floor NAS in the upstair office, and then also to the main listening room on that 1st floor. Then, how much of an audible difference would there be, to say just getting a $99 Airport, and extending the wireless network into the listening room, and hardwiring from that Airport to said media server? I am hoping this makes sense, and appreciate any help. Thanks
  24. Looking for a decent patch panel. 24 or 16 Cat 6 or 6x ports. Nothing expensive. Just something that has worked well for you. Any suggestions?
  25. 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.
