Sound of Quad DAC
The D30Pro is a simple DAC with top specifications, better sound, and a refined build. A perfect partner with the A30Pro headphone amplifier.
The 4 x CS43198 provide a total of 8 full balanced channels. So each channel of the D30Pro will be arranged in parallel by 4 conventional balanced channels. The increase in output capability will bring changes in the sound and the spec will also improve.
USB support DSD256 & PCM384kHz high resolution audio
D30Pro uses 2nd generation 8 core XMOS XU208, USB supports up to PCM32bit 384kHz and DSD256 native. With the help of customized Thesycon driver (for Win 7 or above), your PC will have better performance on ASIO playback.
ASIO settings are too complicated? We also have a simpler usage
How simple can it be? Connect directly to the PC without installing any driveres, set the sampling rate that you want and enjoy!
Selectable output port
D30Pro has full balanced XLR output and single ended RCA output. You can choose "XLR only", "RCA only" or "XLR+RCA" output to meet different usage requirments.
Preamplifier function
D30Pro has a preamplifier function so you can control the output volume on the front panel and also at the remote control. Since it's noise is
