  1. Hello, I just added a new McIntosh d1100 to my system. Generally speaking, it works great, but there are a few quirky things that I was hoping I could get some help with. My setup: Roon core runs on a dedicated Ubuntu Linux VM. I have Roon endpoint on a few Macbook’s, my iPad and my iPhone. I have a Raspberry Pi 2b with the latest build of dietpi on it, and Roon Bridge installed. I then utilize the USB to connect to the McIntosh d1100. Everything is running the latest builds of Roon. DSD over PCM (DoP) is my DSD strategy. Raspberry Pi and Roon Core is hard wired 1Gbps Ethernet My issues: Pretty much in summary the "fade-in" issue described in part 1 of the d1100 review posted here at computer audiophile Whenever I play an album, there is this weird thing where I miss the first bit of the first track. How much I miss seems to depend on source. For 16/44 CD quality, it is the first fraction of a second. For DSD it could be 2-3 seconds. In Roon, you can see the file playing the first few seconds, but the DAC does not lock and start outputting sound until between about 0.5s to 3s later, depending on source.For example, when playing The Beatles Please Please Me album, starting with “I saw her standing there”, you don’t hear the first part of Paul’s count in. When kicking off “A Hard Day’s Night”, you miss the first part of that epic first chord. This seems to happen regardless of what the source is (PCM, DSD, Various sample rates) and on every album There is an intermittent issue with losing lock between tracks of an album. What happens is that at the end of one track of the album, typically during silence or low output parts during the last 3-5 seconds of the track, the DAC loses lock. Roon will still show the track playing. Then, Roon will move to the next track, the DAC regains lock and away it goes. It’s like a little “blip”. Sometimes, I end up missing just the first split second of the next track. This doesn’t happen between ALL tracks, or even between the same two tracks consistently. The issue seems to happen more frequently with DSD or high resolution PCM. Sometimes, other than missing the first second or so of the first track, the album plays fine, with the DAC consistently keeping lock track to track. Other times, the DAC continually loses lock when one track ends, and locks back on for the start of the next track. Other times, it will lose lock after one track, then lock on for the next track, but I miss the first half second or so of the next track. This happens, but not all the time, and not between every track on an album. Very inconsistent. I have tried playing with difference resync timer values, anywhere from 0.1s to 1s to 2s to even 5s just to see what would happen, as well as trying 250ms buffer to no avail. I also tried plugging my MacBook Air running Roon endpoint directly into the DAC, and experience the same problems. I think what I am hitting is a result of how McIntosh implemented the firmware on their d1100. McIntosh’ solution will likely be “use JRiver”, as they have a setting to add 2 seconds of silence between tracks that seemingly fixes this. I don’t want to use JRiver though… Anything I can do or any ideas other than pray for future firmware that addresses this? It sounds GREAT, but losing the first few seconds of every album and the inconsistent inter-track behavior is really taking away from the album experience. Thank You
  2. I'm currently on the look out for a new DAC with DSD 512, Streaming etc. I had never heard of this DAC before but there's a very impressive review here: https://parttimeaudiophile.com/2019/06/14/cocktail-audio-x45-pro-music-player-dac-review/ I had my eyes set on the latest Denafrips Terminator DSD 1024 but the reviewer thinks Coctail is better! And the price is the same as Terminator with loads of extras like CD Play/Ripping and phono stage too (not that I need it). This looks like another great DAC alternative. Anyone with any thoughts/experiences with Coctail DACs especially with the latest 45Pro? Thanks.

  4. Extra Ordinary MQA Easter Egg Introduction With Easter just around the corner, iFi audio has delivered an eagerly anticipated upgrade option as a very special Easter gift. iFi first introduced MQA into its product mix with the nano iDSD Black Label in November 2017. Since then, iFi customers across the globe have been asking when this option would be available in other iFi products. The good news is that the latest improvements to the nano Black Label firmware version 5.30, ‘Cookies & Cream’, does just that. Mqa for all This latest firmware flavour not only adds the latest scoop to the nano iDSD Black Label sundae but it also dishes out MQA (Master Quality Authenticated) audio to the full range* of iFi audio products going back to 2013! This ‘legacy’ update means that you can now download the MQA upgrade (PC and Mac) straight from the Support section of iFi’s website at no extra cost. Mqa optimised Firmware version 5.30 will optimise your device for MQA and can handle up to DSD256 and PCM384. Enjoy the MQA magic like never before. And Finally… None of the above would have been possible without the MQA software engineers who worked tirelessly alongside the iFi software team to make this unique opportunity happen. Thank you. Go to https://ifi-audio.com/audio_blog/mqa-firmware/ to enjoy your upgrade. This firmware provides MQA rendering as this is the ideal solution for portable products and those with power considerations. This means the workload is shared between the host (the computer) and the client (the DAC). The listener will still enjoy full MQA experience. For more information on MQA, go to http://www.mqa.co.uk/customer/how-it-works Legacy *The only exception is the original iDAC.
  5. 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.

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
  6. So I bought a Teac UD-301 yesterday. I followed the instructions and installed the driver before connecting it to the PC via USB. I have my internal sound card set as the default device so no Windows sounds go through the Teac device. I have set the audio output in JRiver to the Teac asio driver. Sometimes it plays songs but sometimes it doesn't and sometimes the Teac doesn't even appear in the list of sound devices and I have to turn it off and on again to get it to show. When it does play, it will work for a little bit but changing song, or skipping the track makes the DAC just cut out. I connected it via the optical port from the optical out on my motherboard and had the same issues, so this isn't a problem relating to the USB input. Another thing that's weird, is that when it does work, I notice the output to be extremely loud, as if it's amplifying the signal. I have it connected via XLR straight to powered monitors and even at quarter volume on the Teac it's much much louder than previous DACs I've used with built in pre-amp. I don't even have the gain set to 0db on my speakers. Saying that, the sound is fantastic. Very detailed and I haven't heard the low end sound so good on these speakers. Any comments would be very much welcome. (oh, and I'm using windows 10).
  7. 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

  9. 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

  11. I live in a small town in Nebraska and need help. I have a Classe Sigma SSP MkII Preamp and a Classe Sigma Amp5. I just bought a Aurender A10. Since both have a DAC should I plug into the preamp or the amp and let the A10 use its DAC. I don't know if I stated the question correctly but please advise. Any help would be greatly appreciated. Thank you in advance.
  12. Hi, I have sparky sbc and try to use I2S connecting to the ess9038pro dac. Unfortunately there is one os moode R43 with general driver which is supplied by allo I guess is working on my System. But DSD was converted to PCM internally. I have tried volumio (installing the I-Sabre plugin which is developed on Pi ) and dietp, both of them have no driver. Em..Is there anyone has the experience to fix this? Or the only way is waiting for allo to upgrade kernel and integrate the driver?

  15. I want to connect a Gustard DAC X26 to Roon. Will an Allo USBridge to do that and serve as a Roon endpoint? Which input/output connectors will I use to connect the Gustard and Allo Bridge? I'm assuming a USB will be used to connect the Gustard to my preamplifier. Correct? Thanks!
  16. A chance to hear what multiple copies of DA and AD conversion do to a music file. I’m making this a poll, but you don’t have to vote. One of these files has been thru 8 generations of copying. So it is a chance to hear what damage is done with multiple digital copies of a 44.1 khz 16 bit file. Would be nice to hear from you if you listen to these to get your thoughts. The three linked zip files will open into three wav files. One is labeled a Reference, one is A and one is B. Either A or B is the same as the Reference file. Please choose in the poll the one which is a copy. The copy has been thru 8 generations of DA to AD conversion. So it should be the odd one out on sound quality. Each file is a 30 second snippet of a full song. I had five files, but you can only have 3 questions in a poll. I'll put up another in a few minutes with two more files.

  18. I have an Allo Boss DAC 1.2 installed on a Raspberry Pi 3B+ running Moode 4.3. 1) If I have J25 installed and power the DAC and Pi from a single 5V power supply, music plays, all works. On the Boss DAC, both the power LED and LED1 light up (green). 2) If I remove J25 and use two 5V DC power supplies, one to the Boss DAC USB-C and the other to the RPi3B+ USB Micro-B, it seems the DAC does not work. Only the power LED lights up, but LED1 remains dark no matter what. When I try to play a music file, I get this error: MPD error Failed to open "ALSA default" [alsa] Failed to open ALSA device "hw0,0" No such file or directory It appears the DAC is not working with J25 removed. What could be causing this?

  19. Were the existing driver and firmware for Allo Piano 2.1 created by using Purepath? If it were, what Biquad filter subtypes were set, Butterworth, Linkwitz, or other mixed? Or what are the filter types of the crossover. The last question is about PurePath. Are there functions to create time group delay between 2 and .1?
  20. Sound Liaison has released a handy sampler to test your DAC's preference. http://www.soundliaison.com/all-categories/6-compare-formats Test your DAC! Format Comparison sampler Which format is best for your DAC? Every DAC has it's own character, some sounds better using PCM files and some sounds better using DSD files...... Some people find the convenience of FLAC files more important. Here on this page is a list containing 2 minutes of a song in 11 different formats. The song is called 'A Fool For You' and is performed by Carmen Gomes Inc. It’s taken from the album 'Carmen Sings The Blues'. http://www.soundliaison.com/studio-showcase-series/276-carmen-gomes-sings-the-blues All the different formats have the same source file, DXD 352kHz (Studio Master). We used the AUL ConverteR 48x44 for the conversion to DSD and Wavelab for the conversion to the other PCM formats and FLAC. When you compare different sample rates always start with the lowest resolution. During listening don't focus too much, hearing is as individual as taste but hearing is also something which can be acquired, like the taste of good wine. You can choose from the following formats: 1. DXD 352kHz 2. PCM 192kHz 3. PCM 176kHz 4. PCM 96kHz 5. PCM 44kHz 6. DSD 256 7. DSD 128 8. DSD 64 9 . FLAC 352kHz 10. FLAC 192kHz 11. FLAC 96kHz

  22. Hey, guys! Just sold my NAD M51 and looking for a new amazingly sounding DAC with maybe a streaming option. Would be nice also if that was capable of DSD 512 and maybe PCM 768kHz, just in case Must have XLR balanced outputs and Toslink input. The budget is around $6000 US. Can go higher if needed. My other components are: Foobar2000/HQplayer MacBook Pro (late 2017), USB digital interface: "Gustard U16", Integrated amplifier: Musical Fidelity - "Nu-Vista 600", loudspeakers: "ProAc D48R". Would be super grateful for all suggestions! Thanks!
  23. Ayre will be presenting prototypes of the new 8 series at the High End show, which will start thursday in Munich. I presume a new dac/streamer/headphone-amp will be part of the 8 series, as a successor of the QB-9DSD. I also would expect to see a new integrated amp as a successor of the AX-7e. But I'm just guessing. I'm curious what will trickle down from the 5 series, and what new techniques Ayre will be implementing. Who knows more?
  24. A bit of reflection between the Ares vs Pontus: Comparing the Ares to Pontus On "OS" mode. Before I go any further, let me just say that my observations about these two pieces is just that; an observation between the two Denafrips. The Ares compared to other DAC that I have heard and owned, is fantastic DAC to own for that price. If one contemplating climb up the Denafrips ladder,great. One may choose to keep the Ares and use it in a second system. But, if one chooses to stay with the Ares ,you are still head of the curve from what's readily available out there. The Ares in its own right is a great DAC for the price. I sold my Schiit Bifrost 4490 after I heard the first notes from the Ares. Now , Ares vs Pontus ( OS )mode, Assuming that the Ares only operates in OS mode. I'm using USB. Pontus is a tad bit under double of what the the Ares can deliver ( meaning: I felt that was getting about 150-60% of the Ares can dish out) On clarity , intelligibility; with the Pontus there is more micro dynamics, more transient, a bit larger stage and more headroom and a better sense of size and scale. The Pontus sonic character is cleaner, livelier, more presence and emotions. Instruments separation is better and the Pontus is a bit more natural . Again, with the Pontus as good as the Ares is, I find myself thinking that as much as I love what I was hearing from the Ares, I found that the Pontus is much more easier to listen to, it's much more easier to follow the music. It's easier to get drifted deeper and deeper into the music , that speaks volumes for the Pontus . Now my question is maybe I should have listened to Alvin and got me the Venus or the Terminator..? We don't know what the future holds, but for now, I am extremely happy to have the Pontus in my house till or if I decide to go up the chain ( Terminator ) I have said before : the terminator must be something very very special if the Ares and Pontus can sound so freaking good. I don't how you guys do it , but, well done Denafrips people , we've been waiting, and you guys have delivered. Next time , Pontus: OS vs NOS
