  1. I use 4.12.1 (as HQP PC) and 4.12.1 (as NAA). The images in both computers are identical, of course. In the NAA USB, I edit the /etc/hostname file so that its host name is "naa". That way, the two computers have different names on the network. I started doing this because I liked the sound better. I can't think of a reason why it should make any difference sonically, and that may have been in my head, but anyway, that combo is fully functional for me. It may work for you too.
  2. I use Windows NAA. 4.12 didn't work for me at all. 4.12.1 is working perfectly so far and suspect it will continue to. Thanks Miska.

    Sorry for the late reply. No, I'm not using CUDA anymore. In my stereo, non-convolution setup, I don't need it.

    The Windows 10 driver should work. It did for me with an Nvidia GTX card.
  5. Working for me too. Zero installation. Zero config. Superb sound. Thank you very much Jussi.
  6. I was able to get that to work too. But on the same server I couldn't get that to work using HQP OS.
  7. @Miska I'm trying to authenticate HQP OS 4.11.2, but it won't take my key. Is that intentional because it's an experimental release?
  8. I've got the new experimental 4.11.2 version of HQP OS up and running. The results are interesting. Firstly, there is a huge EC performance improvement over version 4.11.1. Second, the sound is fantastic. I think it's the best sounding of all the ways to listen to HQP. And it's certainly the easiest to set up to get great results. And now for the bad news... PCM any source rate => DSD5EC x DSD256 x 48 with poly-sinc-xtr 👍 PCM any source rate => ASDM7EC x DSD256 with poly-sinc-ext2 👎 To say it another way, I can do anything with DSD5EC x DSD256. I can do nothing with ADSM7EC x DSD256. Previously, I couldn't get any kind of EC DSD256 to work with HQP OS. When I use any of the other versions of HQP, I can upsample anything short of EC DSD512. So, in my rig, HQP OS sounds great and its EC capabilities are improved, but they still lag behind HQP Desktop and HQP Embedded. DSD5EC is actually my preferred modulator, so if these results hold, I'm likely to keep using HQP OS as is for now.

  10. Thank you. I do use Roon. I'm intrigued. EDIT: I just took a quick look and it's very interesting. Thanks again for sharing.
  11. Well certainly, if you're doing convolution that is another matter. I'm glad it's working for you. Can you recommend a link were I could learn more about convolution?
  12. I'm sure that's true, but I've really soured on CUDA. It's easy to set up and it works perfectly as advertised, and for certain configurations (primarily multichannel) it's probably mandatory. But, I've learned from experience, not having listened to Jussi at first, you need to buy a GPU card that's powerful enough to keep up with your CPU, or it will actually harm your system performance. With my i7-9700K alone, which cost me about $300, I can do PCM (or DSD) at any sample rate => ASDM7EC x DSD256 x 48 with poly-sinc-xtr (!!!) all day and all night. To say it another way, with just the i7-9700K, in simple 2 channel, I can do anything in HQP short of EC DSD512. With any file. I bought a cheap GPU (GTX 1650) and with it in the chain, poly-sinc-xtr crashes like The Hindenburg, but faster. To get a GPU that keeps up with the i7-9700K, I would need to spend something like 800... more.. dollars, or even more than that. And in my 2-channel stereo use case, it would add literally nothing. Others may have a different experiences, or maybe a lot more people are running multichannel with convolution that I realize. 😀 But based on the extensive experimentation I've done since EC was introduced, if you're buying a CPU, I wouldn't recommend buying anything other than a i7-9700K or a i9-9900K.
  13. The differences are insignificant - something like plus or minus 5%. Plus when I looked more closely, I couldn't predict which type of track would generate a heavier load for the CPU. My PCM 352k sample track was actually easier to upsample than most of my PCM 44k files. 🤔 With the i7-9700K with no GPU: PCM (any) => ASDM7EC DSD256 with poly-sinc-ext2 averaged about 35% PCM (any) => ASDM7EC DSD256 with poly-sinc-xtr-mp averaged about 67%. While it's interesting from analytical standpoint, it doesn't matter a whole lot because no matter what file type I threw at it or what filter or modulator I used, or what the CPU load was, the system remained cool and comfortable, there was not a single stutter and the music sounded incredible. The 9700K and the 9900K are both extremely capable HQP performers.

    It may be that the discount is only applicable when upgrading from Desktop V3 to Desktop V4.
  15. You just went from It "borders on necessity" to "order of .001% improvement" in 1 post. 🤣🤣🤣
