Technical Highlights
Proprietary R2R+DSD architecture, true balanced 24Bit R2R+6Bit DSD (32 step FIR filter).
Adopting ALTERA high efficiency chip. 0.005% precision resistor, low distortion, low noise power supply, FIFO buffer.
Each channel is equipped with an independent high-speed FPGA to control decoding
through four sets of 0.005% R-2R network with low linearity error, high decoding speed
and low digital noise.
Dual crystal design, can accurately reproduce audio signals of different sampling rates,
jitter is greatly reduced and stability is significantly improved.
The power supply adopts chopper rectification, customized MUSICIAN brand red shell
capacitors, equipped with O-type 250W iron core transformer, multiple LT1763, LT3045
for 2 times regulator filtering, can effectively isolate the linear regulator for digital and
analog part of the multi-stage power supply, w hich ensures that the DAC can provide
low noise and stable power supply voltage.
DSD1024, PCM 1536KHz supports USB and I2S inputs (audio source needs to be compatible with this unit's interface).
Proprietary USB audio solution based on the STM32 F46 Advanced AMR microcontroller.
No drivers required for Mac and Linux.
