AudioXP Posted July 31, 2019 Share Posted July 31, 2019 Very interesting experiences and information shared here 👍. I’m also sitting at the tip of my saddle to start building my new/next system. How far would an i7-9700k - rtx 2060 (or 2070 (super)) setup take us? Link to comment
AudioXP Posted July 31, 2019 Share Posted July 31, 2019 Yes, sure, I’m following the postings “live” 😉. But there was nothing so far on the rtx < 2080 GPU’s... Link to comment

Volume control doesn't directly affect CPU load, only in case you are hitting the limiter at higher settings. Does this suggest that when upsampling to PCM there will be losses because of volume control? Link to comment

Previously NAA was only capable of output (playback), but not input (capture/recording). So now it is possible to have a network endpoint with ADC, S/PDIF or some other type of input. Does this mean I can connect, e.g. using USB, a computer to the NAA which my HQP server sees as input, and have the server play back the input stream to - e.g. - the same NAA? Cool! Link to comment

Others (including myself) have reported this working on an i7-9700K. CPU load around 50% average per core. Link to comment

But I think better way is to use DSD instead. Depends on the OS and backend, there's practically no technical limit as such. On Linux at the moment PCM limit is 3.072 MHz. On macOS there's no limit (to be exact the limit is a bit over 4 GHz). On Windows the limit is at the moment 1.536 MHz. If needed, it is easy to extend the rates on Linux and Windows. Got a Raspi 4 to work as NAA doing DSD256 with Holo 2 using the latest NAA image. When switching to PCM 1.536 MHz, I got sound, but with a horrible distortion, like a high-frequency ringing. Made me scared to destroy my tweeters. On a NUC NAA, got exactly this working fine (and enjoyed also the SQ :-). Is this to be expected? Can something be tuned...? Link to comment

DSD512 with EC modulators is still not possible as expected. Interesting, thanks for reporting. Is this i7-11700 without K? Have you also tried since-L? Link to comment
