    Dirk, there is no night and day difference and I don't believe anyone really experienced such a difference. I can assure you both are great. From my experience DSD512 feels fuller and deeper which gives a small but significant advantage over 256. I only use poly-sinc-xtr. I just tried it with a couple of tracks, redbook and hi-res. I never used 256 before and I just did a sort experiment so everything I say here is only based on my short testing session. For me the difference is noticeable. It's seems more pronounced playing the hi-res (24/192) less with redbook. I never tried DSD to DSD conversion. I believe some may can claim it subtle but significant some may less notice it. I've met many audiophiles and their experiences are not always the same when it comes to subtle differences (some find it very significant, some not). I am on the subtle differences side. I like ones that brings higher quality so for me it's better significant enough but not by a big margin. If I had no way to compare, I can assure you I could also be happy enough with only the 256 but after the comparison I'm staying with 512. BTW, some people will even tell PCM sounds better. The truth is that PCM sound different. For me it's more like comparing SS to tube. DSD is definitely warmer and I like it better but this can be a matter of taste rather than comparing the same sound and quality.

    Currently the only choice I have is to run Fidelizer to get Latency to the right level. I don't know of anything else that can do it better. I'll be glad to get better recommendations. I don't mind about gaming and music at the same time so for me Fidelizer is the right answer when I want to use HQPlayer and it works perfectly well much better with it than without it. If I want to do gaming I would not mind about Fidelizer. I currently run at "ultimate power" profile which is good for gaming and I have no problems with gaming or stability with or without Fidelizer.

    It stays low and LatencyMonitor is all green. Current latency in low enough and most important stable even during heavy load, so it's good. I am happy I can see and hear the difference. It could be nice to know what is the root cause and what Fidelizer is doing to reduce it. Now that I know what to do to keep latency low, I can enjoy the music without problems or white noise.

    I am still not sure what is causing it. One thing I am certain is that Fidelizer reduces latency. Red is how it looks just after reboot. LatencyMon shows Nvidia and Directx causing high DPC and ISR. I am still not sure if this is an issue and how to deal with it. For now I will certainly continue to use Fidelizer.

    Just to be clear my testing is with "Ultimate Performance" profile. I also found a LatencyMon tool that shows better statistics. It shows current between 10-30 with occasional peaks to 100+. The max is 429 which is related to NVIDIA kernel driver. This seems more reasonable than the checker.

    I tested again. I rebooted the PC and ran the check. This time is was around 4000 micro seconds! Red all over and not enough for real-time audio streaming. I ran Fidelizer and checked again. Back to the 499 micro seconds! Nice. I think this proves that Fidelizer does the job. I can also assure that I need only to run it once after boot and even if I work on the computer for long time it keeps the good settings as was in my first test. It's stable also when playing DSD512 with poly-sinc-xtr. No white noise. Playing now when I'm writing this.

    I get 499 micro second current and 620 absolute on the checker. I am not sure what this means. It does say the system is capable of real time streaming without dropouts.

    Which filter are you using? Does it happen on the same tracks or completely random ones? You may want to test lighter filters. This may give you a clue it might be related to OS load/optimization. You should also use Fidelizer. I tried it again and it seems to be removing the white noise I have it specific tracks. I suspect may be related to OS/USB optimizations/load.

    What you describe is extreme and never happened to me. Something with the setup is probably wrong if this happens. It might be the same root cause that in your case just sounds much worse. Does it happen all the time or just with specific tracks randomly? I do recommend that you try Fidelizer or something similar to reduce any OS load/limitations to see if it helps.

    I also hear white noise in some tracks in DSD only. I use DSD512 with ploy-sinc-xtr filter. I also have ISO REGEN and PPA2 usb card. It starts randomly in the middle of the track. It's not loud but very noticeable. It does not happen in PCM. I found that if I run Fidelizer first and then HQPlayer, the sound is usually clean but I did not test it enough to be sure this completely resolves the problem.

    As much as I am disappointed with not having Linux DSD512 support, I want to encourage and appreciate T+A and Amanero for their efforts to make native support for DSD512 on Linux. It seems the effort and progress done lately achieved good results. I hope it is a good sign. It's already clear that there is a reasonable upgrade path which is great, so fingers crossed for making it work without issues. I think it will make this great DAC a real bargain and will open up many options for using Linux based devices for it so it will be great benefit for everyone if this works out.

    Best CPU for hqplayer

    For me HQPlayer works great with 1920x. As I'm writing this, I am using it to upsample to 44.1x512 with poly-sinc-xtr filter. Sounds great and have no issues with it. I don't even need to boost the CPUs (boost disabled).

    Does anyone know about Lothar writing a program to safely update / recover DAC8 DSD?

    It will be a shame if there will be a v2 or even just new ones sold with updated firmware and no solution for the veteran users that put their faith in T+A DAC and waited patiently for an update. I think T+A must come with a solution how to be able to update safely without forcing us to use MP8 or other expensive or non existent solution.

    I am using AMD Threadripper 1920x which also works great.
