Wow! Now I’ve more reason to up grade my Zotac i5 fan-less Mini PC to a more powerful ones. I was thinking of this:
Not sure it is up to its task to up sample to DSD256 or even DSD512 from Redbook?
The loud ‘pop loud’ seemed to happen when Holo Spring is used in Linux OS, I read from Computer Audiophile, but Windows with the Holo Spring driver shouldn’t have any loud pop, probably some low level clicks when switch tracks.
I’m not sure about Rockna wavedream DAC, there’s no mention in the website that they can do direct DSD conversion in the R2R converter. Is there’s a possibility that Rockna convert DSD to PCM to the the R2R ladder DAC? If there’s the case, there will be little SQ difference between different DSD sampling rate. Again this is just speculation but it will best to ask Rockna directly.
Thanks @Wei_Xia1, looks like I need to build a custom designed PC with i7 and Nvidia GTX-780 graphic card to do DSD512. This is going to be tough. Any off selves ready made PCs that may contain the above components that I can purchase directly?
Sound gallries SGM is a beast audio PC for T+A DSD512, but for that price, I’m not going to pay for it even my wallet is heathy enough. It’s just my personal opinion or my personal attitude towards what kind of things I should splash out or not.
GTX 780 is not good enough I’m afraid, flagship serious double-precision graphic card like Titan is a good choice. But please note that HQplayer relys on CPU more than GPU, so a powerful CPU is crucial. (Jussi is a nice person, mentioned the setup lots of times since so many users ask him the same questions from time to time)
The Noise from the fan is also a factor to consider, CPU water cooling system or low-speed, low noise CPU cooling fan is the way to go.
Hi Jaspal. I upsample PCM to DSD 256 into the T + A DAC DSD.
I don’t upsample native DSD files as Roon converts DSD files to PCM then back to DSD.
I don’t have much DSD material and this “passes through”.
I also use HQPlayer an upsample to DSD512. The HQPlayer NAA is a bit flaky, however… loses the DAC if the DAC is put into standby… have to restart the NAA (and then often HQPlayer) which is annoying…
Hmmm. Have been experimenting more today. For a lot of music, the Roon PCM->DSD conversion does not sound a good as upsampling PCM to 384kHz - which sounds great! Roon output to HQPlayer PCM o DSD512 (closed form, AMSDM7 512+fs) does have the definite edge and is now what I use when settling in for a listening session - but the issues with the HQPlayer NAA not reconnecting to the DAC if the DAC goes into standby (and requiring HQPlayer restart etc.) is annoying…
