Discrete R2R DAC: R-2R ladder DAC converts the digital signal to analog signal by switching resistors' array, it provides a more natural sound. However, this architecture needs precision resistors and deep development to archieve fine performance.

Native 1Bit DAC:support DSD 512 (via USB) and DSD 1024 (via IIS). The DSD streamdecoded by the independent 1 bit convertor without DSD to PCM converting.*Volume is fixed under this mode.

CPLD: Complex Programmable Logic Device:Signal routing; Clock management; 2nd order PLL; DOP decoding; Depop for PCM&DSD.

Clock synthesization: Replace the input signal' s clock with precision oscillators (local or external). Interference from the input source' s clock is avoided. Function off: IIs, AES, COAX, OPT, BT; PCM NOS, 1 Bit Function on: USB & LAN K2, ultra-low noise clock synthesizer: provides precision clock from local oscillators or external clock in.

LPF is specifically designed for the D/A converter using discrete devices. Final parameters of the circuit are adjusted with subjective listening. Different from IC s, discrete circuits provide the possibilities to control every detail in sound and performance. But the parasitic effects introduced huge challenges to development experience and device' s quality.
