Amplifier Chip: Using TAS5508C for digital signal DSP processing and Pre-Amp.TAS5342A for digital signal rear-AMP. It will be through LC filter and then send to amplifier output jack.

Digital Receiving Chip:CS8422.It receive optical and coaxial signal and all signal transfer.

USB chip:TAS1020B. Supports stereo sound 24 bit/96 kHz.For much better sound, we use SDPI output instead of internal DAC output design. Strong anti-interference ability and More High-Fidelity.

HP Amplifier Chip:MAX97220A. Dual-OP amplifier:NE5532 with High efficiency low noise.

Analog/Digital converter IC :CS5341,Accurate to 24 bit 48kHz.Convert AUX signal to digital signal. Then digital signal processing by CS8422
