The input digital signal is buffered and shaped and then demodulated by Saviaudio SA8804 with its ultra low jitter reference clock,
and the decoded by two AK4490s in mono mode for left and right channels respectively. Output buffer utilizes OPA1632 which
impedance is low enough to drive headphones directly.
Precisely designed power supply and layout ensured very high S/N ratio and distortion specifications. A Plitron transformer supplies
the power needed for different sections together with primary regulators followed by ADP124 precision low Low-dropout regul ators
(LDO). ADM7150 precision LDOs with only 1.0 μV
rms noise level were used for the analogue reference voltage (V_Ref) for
AK4490.
Ultimate USB performance was achieved by carefully designed circuits surrounding Saviaudio SA9227 including a customized ultra
low phase noise clock.
Headphone amplifier is fully DC-coupled and fully discrete, JFET input class-A design with low impedance high current output stage
powered by MJD243/253 transistors. Carefully matched and biased for most natural and musical listening experience.
Optional WiFi module is powered by Saviaudio SA9800 which supports playing domestic music files on iOS or Android devices, or
DLNA streams over computer or NAS. All these playbacks support DSD format and PCM up to 32Bit/384KHz.Optional WiFi module
