  1. I have been using ISO REGEN for some time with very good results. Recently I added LPS-1 which significantly improved the SQ. I don't think anyone should go with ISO REGEN without it. My full setup was PC with PPV2 USB->Chord USB cable->ISO REGEN (with LPS-1)->USPCB->T+A DAC8. SQ was very good. No long ago I got a sablon usb cable. This is a hand made special cable that is not completely a standard usb. When I got the sablon cable I could not make it work by just replacing the chord. The only way I could make it work is like this: PC with PPV2->USPCB->ISO-REGEN (LPS-1)->sablon usb cable->T+A DAC. This also worked for me very nicely. I felt it was better than the chord setup. After some time enjoying this setup, I felt something was still not optimal and I tried removing the ISO REGEN using only the sablon usb cable. For my surprise this was noticeably better to me. The sound was crisper with clearer highs/mids and a bit less overwhelming bass. I did not believe it. I change the sablon for chord again and sablon was again better noticeably. Currently my preferred setup is with PC (PP V2) and sablon usb only. The only other thing I changed before all this started are the speaker cables. I used QED silver anniversary which is a very good cable replaced by Clearday double shotgun. The Clearday is a hand made well respectable cable which competes nicely which high cost high-end cables. Maybe this changed everything and caused the ISO REGEN not to shine as before. I know it sounds silly but I can't really explain it. I will continue experimenting but I am writing all this after a few good hours with the sablon only. I am currently certain it works best for me this way. I want to emphasize that before I had the sablon, the setup with ISO REGEN (LPS-1) was definitely the best.

    If it's on the service manual there may still be some hope! 😃 Let's cross fingers and hope it will first work and then see what's the decision on updates. Thanks for the information.

    Unfortunately, I don't believe T+A will vouch for this process even if it's simple and works. It will probably revoke warranty. I wish T+A will provide a process we can do on our own that does not revoke warranty

    I wouldn't set too many hopes on this. We were in similar situations before. Even if this works, it's still very far from T+A adopting it, completing their tests and issuing an update that wouldn't require shipping to them. I am not sure at all that it's worth the effort for them. I can only hope that if it does work on Amanero side, T+A would not refuse it. Even if it will cost them, they should think of all the people that don't buy their flagship DAC because of the Linux limitation. Today there are far more Linux options for streaming than Windows and not everyone can invest in an expensive high-end PC for 512 up sampling. Fingers crossed. Hopes are still very low.

    There were contacts with T+A a few times regarding Linux update but with no success. At first there was hope there will be and update with sending the DAC to be patched or even better a manual procedure. As time goes without any update, I think the chances it will happen are getting really low or even none. I do think it should be T+A's interest that their flagship DAC will have this capability which will definitely make it much more competitive. If they don't do it, I can only guess it's either technically not possible (yet?) or it's not cost/effective for them to handle it (testing, patching, handling, etc.) It may be a good time to check again but I don't think there will be any news. If there was something in this direction T+A would have already published something. I must admit that for me, after building an audiophile PC running HQP, this is less relevant even though I think it can be a great value for trying different streaming options.
  6. I have just switched from a Teradak PSU to LPS-1 for my ISO REGEN. The change was immediate. The sound is now crystal clear, brighter and much more transparent and accurate. It also sounds more airy. In addition the darker, heavier sound I had before is now gone. I still have to get used to it as the clear sound emphasizes the mids and highs. The bass is much more controlled. The only drawback I can see is that the sound in some recording can be a bit too bright. Bass is also less emphasized than I want it to be. Some of the "warmth" the sound had before is a bit missing. I am going to try and replace the USB cable as well. I hope this will improve the sound in the areas I am missing now. Bottom line is that it's a very surprising improvement with significant SQ enhancements. It is definitely the way to use ISO REGEN, otherwise the benefit from it is lacking.

    Nice. It is very interesting to see the Xeon tests. If it works it probably wins for the cheapest option. Processor itself it not that cheap but I guess everything else is.

    I run in quad mode. I have 4x8GB. I also have MSI x399 which has x-boot utility or changing modes. I use game mode. I think it's what you ment. I don't see any difference between game mode or other modes regarding CPU utilization or temperature. I will have to play a bit more with it to see how memory speed between 2400-3200 is affecting temperature and if there is a "sweet spot". I understand the impact of it is not significant but if it's possible to gain something and still be ~50c or below it's good. BTW, I don't see too much effect of the Noctua CPU fans speed. I will try to stop them completely and see if temperature is affected but from what I could see having them at low or high RPM does not affect the CPU temperature too much.

    I am not using dual boot for now. It sounds like a good option. How are you using it? Do you have two separate installations of Windows one regular and one optimized? I am using Fidelizer with max settings. It supposed to do similar optimizations as AO. Maybe it's not the same and it's worth trying AO. I did not see any issue using it for both Audio and other applications so far so I am not sure if dual boot is really necessary.

    For me there is a noticeable and even significant difference in quality between XTR and -2s. Is it worth the cost of a $1800+ PC? This is a matter of budget and other investments already done. If the setup is very expensive and capable of taking advantage of it, it may worth the price. It has to be in proportion to the quality and cost of the complete system. I decided to invest in it both for audio and for other uses so the system is not idle when I am not listening to music. I think that if there are other uses t can justify the investment.

    I am able to run at 3200 without issues. I will keep it for sometime until I understand if it's worth it or not. It does seems to affect temp much but I have to run a bit more to be sure.

    I don't really need it for now. The extra heat as I see now is just 2-3c which is not significant. I do run the memory with higher voltage 1.35v instead of 1.2v and I don't know if this has any implications. I should probably not use it if not needed unless someone has new information in favor of it.

    Does anyone know if it's recommended or beneficial to OC only memory from 2400Mhz to 3200Mhz keeping the CPU at base clock? My DDR4 is currently running at 2400Mhz and supports 3200Mhz. I wonder if I can gain anything from it. If 3200Mhz is not the optimal setting, is there a "sweet spot" frequency?

    Thanks for the valuable info! I actually see my CPU running at ~30% CPU with HQPlayer with boost disabled. Currently I don't see any benefit in the boost. I also ran other performance tests and there is no significant difference. I am sure I can play with it manually as suggested to tweak the performance just in the right balance between power and temp. I will play with it a bit to see what is the optimal settings.

    Thanks Miska. I didn't know about it. It does seem to affect CPU temperature significantly so I prefer not to use it if not needed. I will have to check more into it to better understand it. It may be that even with this option, it may be still fine even if temperatures can get to 60c+. It is mentioned that it is not recommended to exceed 68 on AMD Threadripper. CPU wise it seems to be better utilization but I am not sure it's good enough because of the temperature. I also wonder how this works if memory boost is not possible. Can I get 4.0GHz clock speed on CPU with 2400Mhz memory speed or does it require memory to support it as well?
