Its independent power supply and multi-format outputs (Coaxial, Optical, AES/EBU, IIS) ensure ultra-clean, jitter-free audio ideal for audiophiles and professional setups. While praised for sound quality improvements, driver compatibility issues with Windows 10 may require workarounds. ## Description U12 uses the XMOS professional audio field X-CORE 32BIT / 500MBPS digital signal processing unit, the inside has 8 cores, with powerful multi-core multi-thread processing capability, is being outstanding in industry and provided a USB Audio Class 2.0 digital audio solution. Product Features: Use XMOS programs to support 32B 384khz asynchronous 2.0 (recommended ASIO output when using USB) using an independent power supply. Built-in sealing ring cattle, multiple sets of multi-level regulation. About the importance of independent power, I believe we all know. optimize the design of the audio clock circuit using 0.1PPM precision active crystal to provide a more perfect clock signal to digital audio. Provided for by the two crystals were 44.1 / 88.2 / 176.4 / 352.8Khz and 48/96/192 / 384Khz series rate signal only after the selected clock rate selected work, work another one audio clock stop, put an end to the mutual interference may bring work simultaneously when the two clocks. A total of four kinds of output: Coaxial (RCA), optical fiber, AES / EBU, IIS (HDMI port) Coaxial fiber AES / EBU output formats IEC60958 and AES3-r2009 standard limits the maximum support 24Bit / 192kHz; IIS can transmit 32B 384K smart switch, USB has a current interface to boot. Interface with the computer switch and switch machine (computer to be set off USB power failure), or unplug the USB cable directly to the shutdown. Review: The U12 made my Redbook FLACs sound better. - For me the U12 is definitely worth the money. Previously I ran my Windows computer's native optical S/PDIF signal into my DAC (Schiit Bifrost Uber). The U12 is incrementally - but noticeably - better. Redbook played from JRiver Media Center sounds bigger, blacker, and more rounded. It's simply closer to DSD, and much more pleasant to listen to. I'm genuinely impressed. The fact that it has pulled my 44.1 FLACs a bit further away from harsh treble hell makes it a keeper for me. The U12 sounded a bit bright/harsh upon first use but it cleared up within the first day. Expect some burn-in time. The device itself functions flawlessly, accurately displaying all sample rates from 44.1 to 384, DSD64, and DSD128. I do appreciate seeing the sample rate display, it's helpful to know what's actually being fed to the DAC as I fiddle with various software settings. The only difficulty is getting the XMOS USB driver to install. It comes included on CD but Norton Anti-Virus flagged it as a trojan horse. (I imagine it's actually safe.) In any case I used the Luckit modified driver, which you can find in this Head-Fi thread: http://www.head-fi.org/t/736294/gustard-u12-usb-interface-8-core-xmos-chip/30. Worked great. Bottom line - I'm very thankful this product exists at this price. It has made my Redbook collection more enjoyable. Review: Won't Work with Windows 10 Any More!!! - I loved the sound when it worked, which was about 10 days. My Windows 10 laptop processed an update and rebooted. The U12 has refused to reconnect to the laptop. Disconnected USB and reconnected. Deleted and reinstalled driver. Shows up on the device manager, but is highlighted because the driver (v3.34) is unsigned. So, apparently the update to Windows 10 prevents devices from using unsigned drivers. The U12 is now a paperweight until they update the driver..which they don't plan on doing. Their advice is to turn off driver certification, which involves rebooting the laptop using Shift+Restart and navigating through some menus. And you'll have to do that every time you turn off (or restart) the computer. NO THANK YOU!

Back it goes... ### ⭐⭐⭐⭐⭐ effortslessly easy on Mac *by R***U on April 27, 2016* I am pairing it with Macbook Pro at one end and Bryston BDA-1 on another, using High grade USB cable and COAX cable respectively. Software I am using is jriver. Now, to start with.. in Mac it works out of the box. No driver is needed. however USB on Mac currently support output upto 192k (Midi) ( if all system sounds passing through Gustard u12). however when playing media using Jriver you can push much higher Bit rates and depth like DSA etc and it shows the reading of Bit rate played on etc on its mini easy to read display. Since its feeding to Bryston so I had to restrict Jriver to push only upto 192k so that bryston can understand and decode it and then pass it to my Preamp. Now, as you can see... with Mac I didn't have to struggle with drivers & so forth.. setup was done within 10 minutes. over 30 minutes worth of efforts went into tweeking the system to restrict it to only send 192k which in not due to Gustard but due to my DAC in picture ( which is Love for its tonal quality) . Having said that DAC shook Hand with Gustard like a lost brother and instantly tuned in to Better sounding music. No Jitter, Connection lost or any other problem so far. it just works every time I switch to Gustard from my Wadia. it was improved the tonal quality of media being played. made with quality materials inside out.
