UD-01 (USB DAC)

　Characteristic

　　UD-01 turns mundane desktop and personal audio into exciting high-end performance (The DAC –characteristic architecture is built around Burr-Brown PCB2702E DAC chip (dedicated two channel audio has large internal strong buffer to store up audio packets). Low pass filter: Burr-Brown OPA2604 acts as output stage preamp and taking out the residual digital garbage and turns the audio signal into more analogue sounding stream to guarantee sonic excellence. DC servo: Texas TL072 low noise JFET op amps assigned to DC servo circuit. Coupling capacitor is to avoid harmful sonic impairment.
