  1. I haven't bought my QB-9 "Twenty" yet because the situation in Brazil is not very good. Is there still time to buy? Are there any plans for upgrade sales to be stopped?
  2. 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?
  3. 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
  4. I will wait to go through this crisis moment to buy my upgrade. In Brazil things are complicated.
  5. 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
  6. 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
  7. 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
  8. 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
  9. 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

  11. 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
  12. 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...
  13. 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....
  14. 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.
