The modular amps can be upgraded for phono playback thanks to an extra slot in the system.
The C 375DAC and C 356DAC from NAD pack the same kinds of components and features that you'd expect from the company's integrated amps. But they also bring something new to the table - 24/96 DACs for all of your USB connected devices that promise to get richer sound out of your compressed audio files.
The C 375DAC and C 356DAC come equipped with 24/192 dacs for the rest of your audio and utilize OPAmps to provide optimal power. You'll find an RS-232 interface and 12-volt trigger, allowing for custom setups and a modular design so you can upgrade as you see fit.
NADs integrated amplifiers run $900 for the 356DAC and $1,600 for the 375DAC.
