Reference DSD1.1 pro is a high performance D/A convertor for CAS purpose. We use the advanced X-MOS module to support DSD playback up to DSD256 and support Native DSD streams mode. The Reference DSD1.1 pro uses the latest and more powerful DAC chip AK4497. It support some new provides new modes such as "DSD direct" and "low dispersion short delay". The "DSD dircet" mode can let the pure orignal DSD signal direct to outputs and the "Low dispersion short delay" for PCM digital filter can let DAC chip close to R2R operating mode. The DAC chip board can easy to remove and fix to do update in the future. It also uses the special "USB grounding isolation design", which keeps the noise away from the computer's USB. It supports free driver for apple device (MAC/ phone/ pad) and our X5. There is a special tube buffer design before the RCA output, which makes the sound better.
