After rolling through a bunch of USB interfaces including 3 different John Kenny's, M2Tech Highface and Evo, Audiophilleo 2, Musiland 02 and Musiland USB 3.0 USD. I settled on the Musiland USB 3.0 as the best sounding. Made better with a Aqvox linear power supply. I've been running this for over a year and really happy. But heard about this unit and just ordered one, wanted to see if anyone has tried it. Looks promising: - Native 32 bit 384Khz 8 X-core XMOS chip. Multi-thread. USB class 2.0 Async. - Seperate 0.1ppm TCXO clocks, Temperature Controlled High Precision Active Crystal. One for each clocking ratio. - Independent Linear Power Supply. Sealing Torodial Transformer, Multiple Sets of Multi-Level Regulation - Four outputs: Coaxial (RCA), Optical Fiber, AES/EBU, IIS (HDMI port). - DSD support to 128. PCM to 384K. - Latest XMOS Thesycon ASIO v1.6.1 drivers, strong driver support for future Windows versions. http://www.kidultdiagnostic.com/blogs/new-release-gustard-u12-native-32bit-384khz-xmos-0-1ppm-dac/ Pics to follow.
