Adopts XMOS chip for USB signal input, PC jitter-free USB Audio with Asynchronous Transfer Mode, provides I2S interface for decoding, can support up to 192KHz/24Bit USB signal, support WASAPI, ASIO, KS Kernel Stream Mode.
Adopts high-performance D/A chip: WM8740*2, can supports up to 192KHz/24Bit I2S signal;It adopts 12AU7 tube for pre- amp, 6C19 tubes each channel for post- amp, making sounds soft and attractive.
Adopting capacitive coupling output to dispense the limit of output transformer and make the frequency response of the amplifier more close to the amplifier limit of the tubes; Adopting ELNA, NICHICON, RUBYCON and other famous capacitors.
Adopting the high-quality E type transformer with low noise and low leakage flux specially for transistor amplifiers; Using cherry wood for its lateral plate makes it look very upscale.
With 1 way Single-Ended RCA input, it can be used as independent headphone amplifier.
