Design Features
Independent power supply to digital circuit and analogue circuit, left/right channel
of digital circuit, DAC circuit and analogue circuit are powered by independent
power supply system, reduce power interference among different circuit, and
make sure all components will have clean power all the time.
Employ state-of-the-art high resolution USB Audio technology, will accept and
decode Hi-res digital audio bitstream through USB interface, a centerpiece of a
high-end CAS playback system.
Supports DoP (DSD over PCM) on Coaxial digital input, decode DSD at 1 bit
(require front end digital equipment supports DoP output on Coaxial)
Versatile to fit different needs, user can select RCA (single-ended) or XLR
(balanced) output for their needs, and the RCA output provides choice of
transistor or vacuum tube output for different sound signature.
Output can be configured as Line out or Pre-out (with volume control), can fit into
different systems easily.
