  1. I have to say I have it over 2 months and I tried using it with PUC2 lite and my T+A DAC8 DSD. Unfortunately the sound is best with PUC2 only and without the ISO REGEN. Sound without it iis clearer and highs are better. With ISO the lows are more dominant and may be a bit better but the highs and clarity is not as good. I gave it enough time to “burn” and it seems to stay the same. Currently I am not using it. Since PUC2 works only up to 192KHz + AES, I cannot use it for DSD which works USB only. For this the ISO may work better then USB only but currently I am not using DSD. For me at this point, it is a dissappointemt as I was sure it will improve the sound in a way I will like to use it. I hope nothing wrong with it as I heard some had issues. I have to add and I using it with TeraDak PSU and not the famous LPS-1. If this is why I am not liking it better, it’s means I have to spend much more than I wanted for the promised sound upgrade.
  2. T+a dac 8 dsd

    If I understand correctly, the T+A DAC8 DSD does not any external power for USB. The DAC works fine with just a simple cable between the DAC USB input and the computer USB so nothing else is needed.

    @Abtr, can you describe which DC-blocker is installed and how you installed it. I am interesting in the BPS solution and if it works great including DC-Blocker I may go for it. In addition, are you using anything else on the USB chain? Does it help or is the Airlink briniging the most significant improvement?
  4. T+a dac 8 dsd

    I also tested all PCM filters and with my system and speakers which are very revealing and forward (Yamaha NS 1000M). Bezier 2 is definitely the best. It is slightly better than Bezier 1 but add a bit more clearness/crispness that for me makes a difference. I have now settled down on it and I don't change it anymore.
  5. After a couple of months playing with it, I am currently settled on PCM with PUC2 lite which gives me a fantastic sound, clear, transparent, balanced, with good lows, mids, highs, and everything seems to be in place. I did not go for DSD yet as I don't have the right HW to do upsampling. I also got a new ISO REGEN after reading so many good review about it. Unfortunately it does not seem to improve the SQ. Without PUC2 it may have a subtle improvements mainly on the lows. With the PUC2 is does not sound as good. The mids, highs are more veiled and not as clear and without it. It will be hear more experiences with T+A DAC and ISO REGEN.
  6. T+a dac 8 dsd

    Any update regarding the Linux (Amanero) DSD512 support?
  7. I am investigating how to improve the SQ from USB for my DAC8. Until now I have used a decent Chord USB cable, Jitterbug, ISO REGEN + USBPCB + TeraDak LPS, PUC2 lite + TeraDak LPS. So far my conclusion is that using a PUC2 lite with AES connection give the best sound. The only drawback is that it is limited to PCM 24/192. Sound quality is great, very clean, vert balanced with every instument in place. Using ISO REGEN or Jitterbug did not work for me. Jitterbug did not add or removed anything. ISO REGEN which is highly praised, sounds a bit better than USB only but it is not very significant as I expected. ISO REGEN + PUC2 lite is even more surprising. It is not as good as PUC2 alone. It emphasizes the lows but veils a bit the highs. It would nice to hear similar experiences and any recommendation for USB/DDC components that did significant improvement the T+A DAC SQ with USB. I am not looking for subtle improvements but ones that are significant, similar to what I get from PUC2 lite. Experience using Isolated/balanced power can be interesting as well.

    Too many options... It will be good if anyone can compare BPS with/without iFi, EITR, ISO REGEN, Singxer or similar. If a good power solution like BPS gives enough improvement that makes everything subtle or even worse than it may be the right way to go.
  9. Schiit EITR

    Oh no! Another new device for SQ. My chain is becoming so long I can almost put it in the next room I wish there was something definite that we could just use and enjoy the music. For now it an endless chase the does not seem to end. The sad thing is that all these improvements which some do matter are going to cost more than the system itself.
  10. Schiit EITR

    Thanks for the info on BPS! Sounds like it does make a noticeable difference. Can you elaborate a bit more on the SQ improvements? I mean what are you experiencing better than before (things like: clarity, sound stage, dynamics, highs, lows, transparency, separation, etc.) Did you had a chance to compare it to anything else like EITR, ISO REGEN, Singxer, etc.?
  11. Schiit EITR

    @Abtr, Good to hear positive impressions on the BPS1500EU. I am also interested to know if I should get one: Is it humming or emitting any audiable noise that may need to put if far away? Does it improve the SQ alone or does it still need EITR so similar product? Did you connect all system components to it (AMP, PRE, DAC, etc.)? It will be good to know how much you recommend it and how much SQ improved without adding anything else to it. I wonder if this is a better investment than any of the USB components like EITR or ISO REGEN or similar products.
  12. If power supply plays such a big role in SQ (and I believe it is), we may be wasting time and money in the wrong direction. It will be good to hear experiences of people using BPS or anything like it. If this has much more effect than all USB devices it may be the right way to go instead of spending so much on different components that may or may not affect USB SQ. For now I am very pleased with the PUC2 SQ but it has it's limitations in playing hi-res formats and DSD. I wish there will be more concensus on what is the right solution or direction for significantly improving SQ as for sure it can be improved. For now I am not sure where to go from here. I can wait more to see if ISO REGEN will improve or try to investigate power supply directions. Unfortunately all these experiments are not cheap. I hope we'll to see some more BPS or other power supply solutions experiences/suggestesions, to better understand what is the right direction to go.
  13. In my system with PUC2 lite->T+A DAC8 DSD (AES), the addition of ISO REGEN does not improve the sound, at least up to now. I gave it a few more hours to run as was suggested but it's still sounds more pronounced on lows and with less crispness in the mids-highs. I will still give it more time to burn-in and I can only hope it will get better. I also tried it a bit without PUC2 on USB connection. It sounds good but not as good as the PUC2 alone. Currently the PUC2 alone wins in my system. I hope this is not related to the TeraDak LPS. I really don't want to buy any expensive LPS that costs more then the ISO REGEN itself. I do hope there will be improvement soon and that ISO REGEN will do the difference many people say it should do.
  14. Thanks for the burn-in tip. I did try one thing that seems to make things better. I removed the Jitterbug piece I had on the USB cable before the ISO REGEN. This made things better. Now it's less veiled but I do notice a bit more dominance on the lows. I still cannot say it's any better but the clarity and transparency are there which is good. I guess this either has to improve with time or I have to get used to it (or not). It's probably the lows that currently make the difference. It seems warmer and more tube-like than before. I have to admit that I do like the sparkle of accurate and crisp highs so I hope it will get a bit better in the mids-highs. Bottom line, with Jitterbug out, I think it's currently more or less in the same level as without but different. I guess some may say it sounds better some may say it's not but nothing dramatic either way. As suggested, I will give it much more time and hope it will either get better or I'll get used to it
  15. I just got my ISO REGEN. Until now I was using PUC2 lite which significantly makes the sound better. With the PUC2 I get a very clear and detailed sound on one hand and relax and not fatiguing on the other hand. Now I added the ISO REGEN before the PUC2 to improve the USB feed to it. I was surprised to find that the sound with the REGEN was not any better and even more veiled than without it. The difference is not big but it definitely it sounds better without. This is very strange to me as I don't see any reason it will not improve or at least stay the same. I use Teradak LPS which may not be as good as the recommended Uptone one but I still think it should not be like this. I will try to use the ISO REGEN alone and see how it performs to eliminate the effect of the PUC2. I hope this will work so at least I will be able to use it for the USB path. It will be interesting to hear if anyone had a similar experience (either with PUC2 or any other DDC) and if there is a chance it needs longer burn-in time to improve.
