32Bit/768KHz DSD256 d/a convertor

Reference DSD1.1 is a high performance D/A convertor for CAS purpose. We use the advanced X-MOS moudule to support DSD playback up to DSD256. The Reference DSD1.1 has a Hi-Speed Audio USB2.0 interface for the digital input from computer. Support Native DSD streams mode, this is pure orignal DSD signal which never be converted. It also uses the special USB GND isolation design, which keeps the noise away from the computer's USB. It supports free Driver for Apple device (MAC/ phone/ pad) and Andriod device. The clients can use APPs to play DSD and PCM files in the apple and andriod phone and Pad. There is a special tube buffer design before the RCA output, which makes the sound better.
