  1. I'm trying to make the new driver version (4.67) work on my QB-9 (model 192/24), but with no success. I tried it on Windows Server 2019 and Windows 10, with JPLAY FEMTO, JRiver and foobar2000. In none of them did I manage to extract sound. I also tried ASIO, Kernel Streaming and WASAPI modes, also without success. I always get an error message and, in the case of JPLAY FEMTO, the computer crashes and stops working. Any tips? Or does the new version only accept the QB-9 Twenty?
  2. My exhaustive tests with dozens of storage devices were performed, mostly, at the time of JPLAY v. 6.2, where I used it in conjunction with MinimServer. At that time, I experimented with numerous filters with AVconv and FFmpeg and a lot of other things. Local storage (SSD, not HD) has always been superior (and I still think SSD and SATA cable are better than M.2 NVMe), with the computer itself managing the library and playback. More than that, I've always preferred the exclusivity of assignments, and for this reason I consider the result of the SATA connection superior only for transferring mu
  3. I will wait to go through this crisis moment to buy my upgrade. In Brazil things are complicated.
  4. The integration of the personal computer (PC) into the home stereo system has provided a revolutionary way to purchase, organize, and play your digital music collection. The Ayre QB-9 digital-to-audio (D/A) converter provides an equally revolutionary way to play back your music files with unprecedented fidelity and realism. Connected via the ubiquitous USB port, the QB-9 generates the master audio clock and requests the data from the computer at the correct time for jitter-free playback of your music. Apple computers can use the standard device driver, while Windows PCs must install a free dow
  5. Not every manufacturer develops its own driver or sufficiently improves a generic driver (such as Thesycon) to extract the most of hardware quality. So, it's very difficult to assess what can be better. The drivers from Hegel, Wyred4Sound and the old USB controllers from Schiit, for example, are not as improved as possible. But, even so, I always find them more reliable. Regarding the order of installation, I'm not the greatest expert on this, but I believe that the JPLAY FEMTO needs to be installed first. Audiophile Optimizer doesn't ask if we want to uninstall JPLAY, but rather d
  6. Hello. I did very extensive tests with every smartphone/iPhone software I found. I can't say that they were all conclusive, but I managed to make a good impression of them. So, here are some reports: 1 - MConnect is the worst software I've tried, with a good margin. I believe this is because, with MConnect, the mobile device becomes the signal path, so the wireless signal (which I try to avoid as much as possible) becomes fundamental, the quality of the device too, and in the end, we create a path that doesn't seem to be the best. It contradicts what we have as most perfect in audi
  7. I've been experimenting with computers for over 10 years, and because of that I've experienced a lot and have my convictions consolidated. I started from a notebook, went through countless desktops, and halfway through I bought SOtM tx-USBexp, a real bargain for what it delivers quality. As in Brazil buying things in dollars or euros is always very expensive, and I bought a used SOtM, I always found it very cheap for what it plays. At that time, there was no JCAT USB Card FEMTO, only the first version, which cost more, but not as much as the later launched SOtM sCLK-48.0, and this was what mot
  8. The ATX adapter is the Mini-Box M4-ATX, which I prefer to use in conjunction with other elements to power the motherboards. In my experiments, I saw no advantage in using independent power sections for them, especially because I don't use M.2 SSD and because the processors have an independent 12v power path. Today, if I were to buy an ATX DC-DC adapter, I would buy the M3-ATX, as it is much smaller and fits directly on the motherboard. It's an application that I made after a lot of experimentation, but without any pretension of being correct in something. I only achieved a superior result with

  10. Until today, I've tried foobar2000, JRiver (several versions), Roon, Album Player, KODI, I've tried TIDAL, HySolid and several other software and operating systems (AudioLinux, Euphony, Volumio, Daphile and others). Undoubtedly, JPLAY FEMTO is the most critical in terms of synchronization and integration between hardware and software, as it requires extreme levels of latency and buffer that only the best DACs and drivers can achieve. But, once this perfect integration has been achieved (with the possibility of using the DAC Link parameter at 1000Hz and the lowest buffer and latency as possible
  11. I bought the JCAT USB Card FEMTO a year ago, and I'm still postponing the purchase of the Net Card FEMTO. I need two units., but it seems better to wait a little longer, hehehe...
  12. I had scheduled the upgrade for February, but a number of things happened and I'll have to postpone it a little longer. I don't want to delay, as I'm very optimistic about the improvements. I currently have version 192/24, and tell you: try the Synergistic Research Orange fuse. If you are surprised by the QB-9, wait until you hear it with this fuse... Please, keep the topic updated with your impressions and also with comparisons with other DACs....
  13. A friend installed the new version of the driver and was able to get his QB-9 DSD to work. I don't know if the problem is only in version 192/24 or if it is on my computer, but I'll reiterate the experiments calmly and post again here.
  14. I tried driver version 4.67.0, but it didn't work. In principle, I experimented with foobar2000 and JRiver, but neither could play sound. I tried using Kernel Streaming and ASIO modes, but none of them worked. foobar2000 gave the message "Unrecoverable playback error: Could not create ASIO buffers". JRiver gave the message "Format not supported". When I reinstall version 1.26S, everything works again. Too bad. I'd like a more updated driver, because this old one (1.26S), still prepared for Windows 7, causes me many problems installing on Windows Server 2019 Datacenter Core Mode. Do
  15. In fact, the version of QB-9 reviewed at Audio was 96/24, as the review was conducted in September 2009. The 192/24 version only came in 2011, the F revision, and the DSD version in 2014, the J revision. I didn't see any direct comparisons between QX-5 and QB-9, just saw the notes on the Audio Magazin list (I attached a photo from the magazine). I'd like to see QB-9 "Twenty" being reviewed again. I believe we'll have a nice surprise.
  16. As far as I know, the QB-9 "Twenty" is superior to the Ayre DX-5 (I don't know if I can reveal the source of this information, but maybe Ryan can help us), which was an equipment that by Audio Magazin had 130 points for the XLR output and 125 points for de RCA output, compared to the 125/120 of the QB-9 192/24. The DSD version has never been evaluated, but it would be interesting if the latest version of QB-9 were reviewed again by the magazine, with good digital transport, excellent cables and the latest driver version. I'm sure we'll be surprised just as I'm impressed daily with this DAC. I
  17. I've never seen an advantage in handling files for DSD conversion and applying particular filters/algorithms when DAC is not no-oversampling. If QB-9 "Twenty" continues to apply its own filters or its own upsampling/oversampling, even when using external conversion, there should be no advantage. Personally, I prefer to always work with files in their original format. But I think this is very relative from system to system. Sabre chips usually deal better with DSD, and I believe bit-by-bit data transmission is less dependent on clock synchronization between devices compared to 16 or 24-bit clos
  18. Although Twenty was announced to be the latest hardware upgrade planned for the QB-9, it would be perfect if we could continue to receive improvements through the firmware.
  19. I forwarded two emails to Ayre, as requested, and so far have received no response.
  20. Hello. Unfortunately my testing period with Roon is already gone. At the time, I had tried Roon against JPLAY FEMTO, and I considered Roon worse in sound quality. Either way, even better, I'd never pay the price for its lifetime license. I didn't understand your question exactly. On my computer I use only Windows Server 2019 Datacenter in Core mode, Audiophile Optimizer v. 3.00, JPLAY FEMTO and Minority Clean, all running from RAM, besides making over dozens network and BIOS adjustments. Thus, the SSD works exclusively for transporting music files. But, let's leave that t
  21. I downloaded the latest version of Euphony and restarted the experiments. I set it up as I had done before and added the suggestions colleagues left on the topic. Improved, but aspects that don't relate to what I wrote that Windows is superior. That is, it continued to play incorrectly from the timbre point of view, without the same dynamics and articulation of Windows and with a remarkable poverty in textures and harmonics. With the monitor connected to the computers, I tried everything without success. It was the last time I tried a Linux.
  22. For a long time I tried to promote electromagnetic shielding and electrical isolation among countless of my DIY devices, with particular emphasis on what I've built most in recent years: dedicated computers. My practical experience from power cords, electrical wiring, and computer construction indicates that for all system items, there's an optimal point of filtration and isolation. If you add too many filters (like the Nordost Qv2, the iFi AC iPurifier, or even regenerators like the PS Audio P5 and P10), the sound system tends to work as perfectly as it would if the electrical installation wa
  23. Any way to upgrade in Brazil? I have version 192/24 and would like to buy the "Twenty" version.
  24. On my computers (using JPLAY FEMTO dual-PC configuration, and also set up Sylus in "Server" and "End Point" modes), I have six power supplies specifically tuned for the best sound: two for processors (sigma11 with special components), two for motherboards, one for SSD (ldovr single rail) and one for JCAT USB Card FEMTO (ldovr single rail). I have two more ldovr for the JCAT Net Card FEMTO, but I haven't bought them yet. So, from what I've already set up and what you're saying, without changing my current hardware to a more powerful, I can only set the processor core assignments/frequencies and
