The DAC 1 bypasses all the analog circuitry in your PC and transmits directly to your Hi-Fi using the native digital format for the best possible sound. Once received at the DAC 1 receiver, the digital signal is converted and sent as an analog signal to your stereo amplifier. There is also a coax digital output that allows downstream digital processing. Analog conversion uses premium BurrBrown OPAmps and 24/192 DACs with selected passive components in a proprietary circuit. This attention to detail is unusual at the price and is the reason for NAD's incredibly musical sound.
