  1. In regard to the Dave (and other current Chord desktop dacs) feeding in a 16fs signal bypasses the first WTA filter process, but there is further upsampling to a higher rate (11.2mhz), before the data hits the noise shaper which runs at 104mhz. It's not entirely clear to me what bit width is used for these internal stages, but the output is a 5bit format at (logically) 104mhz.
  2. Hi David I'm sure you know what your app looks like🙂 My issues are not with the visual representation - I would have made other aesthetic choices but I can forgive the choice of layout and fonts. My issues are: Why di I need to launch an installer every time I want to stream? Then wait while, briefly, a white shape with a logo-y thing appears, spins a bit then vanishes. Then, for many seconds there is not indication that anything is continuing - the process could have failed completely. Some indication that stuff is happening would be nice. Once
  3. Hi Mark I really like Qobuz, don't want to lose what if offers, but need to find a way around this issue (unless they fix it quickly, but I have no expectation that'll happen). The RPI route is a possibility but I am trying to avoid re-introducing lots of elements prior to the arrival of my Dave dac. When I trialled Qobuz streaming a few months ago I did use the Logitech Media Server integration and it may be worth going back to that, so thanks for the nudge. However, Audirvana does offer the chance to utilise EQ plugins and decent upsampling along with hopefully a mo
  4. I have been buying music from Qobuz for a long while, and recently took a subscription for the streaming service. I don't use Roon or any other form of library integration. The "app" on Windows 10 is garbage. Poor navigation, takes ages to initialise, and doesn't seem to handle mixed sample rate file streaming well to my Chord HugoTT2. It seems to get confused and the music replays at low speed so everything is dragged out - an interesting effect, but wears thin quickly. I shall buy an Audirvana license and see if that works better, otherwise I shall think seriously a
  5. I have no problem enjoying the TT2 - it's pretty decent. Apparently Chord have issues with metalwork, maybe they get them machined in europe. That is not good. Maybe clasp a hand over your left ear... If the Ultracaps are fully isolated (no common ground to cause a short) you should be OK, but choose the 14v path, stay away from overvoltaging - manufacturers can usually tell when something got burned from to much voltage and it messes with their kindly nature regarding warranty claims. Test well before attaching to your good kit, make sure the voltages ar
  6. I'm not generally known for my patience, this is gonna kill me! If I find a black one in the UK used, I may have to have a word with my dealer (who is great, TBH).
  7. This thread is not healthy. I ordered a Dave a couple of days ago (partly because of Ray's continuing adventure) and now I have a ten week wait. I can build a lot of power supplies in ten weeks.... Or may I should just go listen to some more music on the TT2. Taking care of the DC in on the USB side brought an unexpectedly big subjective improvement there.
  8. View Classified Schiit Jotenheim R - No Dac A few months old, excellent condition. This is an excellent way to get sound out of your Raal SR1a "earspeakers". No dac fitted, but can be retro'd in, I believe. Original shipping box (nothing fancy, this is Schiit, but functional and sturdy). Price is £500.00 plus shipping in UK.

  10. Download the HQPlayer trial version - the manual is included in the installation folder. There is a list covering the basic nature of each filter and modulator. Pretty basic, but help to give you an idea. I am using the program in pretty much this way, upsampling PCM into a Hugo TT2. I haven't tried the M-Scale yet (Covid interrupted the fun) but upsampling to 705/768k using Sinc-M or L (or Polysinc Long) bypasses the first stage WTA filter and adds markedly to the depth of the reproduction.
  11. Yeah - powerful tube amps of suitable quality are uncommon and uncommonly spendy. Chris probably has access to the best, but a pleb like me ain't planning on dropping that much moolah. I never messed with the Ncore input buffer, and yes they are pretty clean and transparent. Never convinced me they were "better" than a good Class A/B amp, but still pretty good. Purifi is a project for 2021 (assuming there's still civilisation out there to bring stuff I want to my bunker...) but I think the Chord DAC has enough voltage out in AMP mode to bypass the buffer stage. From wha
  12. I've been thinking diy Purifi too, the older Ncores worked pretty good into the Raals, but the JotR works better for me. I'm thinking Hugo TT2 (unless that gets replaced Mola Mola stylee) in AMP mode into the Purifi module without buffer. Question is just how transparent that interface box really is.

    Hi You may find that the cpu load may show as 50% but the core(s) running the ASDM7EC modulator is not able to process fast enough to keep the output realtime which causes the stuttering you are hearing. 4.2ghz is possibly not fast enough for this process. It may help if you are running a lightweight filter, but you may simply need to try a less heavy duty modulator.
  14. To be pedantic (sorry) - USB is serial too. Universal Serial Bus. SPDIF sends the data in l/r frames and the dac uses the frame rate to derive the clock rate. USB sends data in bursts at a fixed rate (24mhz iirc) and the dac buffers them. The sample rate is explicitly communicated in each burst. The clock renders the data into frames, reads out the buffer (again serial) into the decoding circuit and sound comes out the other end. So the USB data clock should not matter at all - but many discover that it does.
