D30    24bit/192kHz S/PDIF & USB DAC, support DSD64 and DSD128
DSD provide higher resoluction than CD


DSD64 and DSD128 which supported by D30 is 2.8224MHz and 5.6448MHz sampling rate while a CD disk is only 44.1kHz.
DSD providing more detail than a CD disk.
Support most of digital inputs

D30 support USB, Coaxial and Optical inputs with the rate of 16-24bit/44.1-192kHz.

USB support DSD64/DSD128(DoP or ASIO Native).

  Simple operate  

D30 only have 2 switch and 2 LED, these are already enough for operate and display. You will feel easy to enjoy with.

  No pop noise  

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.

Full Aluminum Shell

D30’s shell is just like our other products, made by machining center and engraved by high power laser.

XMOS asynchronous interface

XMOS is famous for ultra low jitter. It provides DSD64, DSD128 and 24bit/192kHz support. It also support ASIO audio software interface.

Cirrus CS4398 DAC and HIFI components

D30 use Cirrus’s CS4398 DAC to decode.

D30 also use HIFI components to get better performance. KOA resistance, WIMA capacitance, EPCOS capacitance, nichicon FW capacitance and OPA2134 HIFI OP. Finally D30 reached a lowest THD+N 0.0004%.
