? D30 support USB, Coaxial and Optical inputs with the rate of 16-24bit/44.1-192kHz.
? D30 only have 2 switch and 2 LED, these are already enough for operate and display.
? For technology problems, most DAC will has pop noise while switching DSD and PCM. We design a circuit which made of relay and electronic switch, it cut off all pop noise of D30, including turning on, turning off and switching DSD and PCM.
? D30's shell is just like TOPPING other products, made by machining center and engraved by high power laser.
? XMOS is famous for ultra low jitter. It provides DSD64, DSD128 and 24bit/192kHz support. It also support ASIO audio software interface.
