In its simplest form, the BluOS™ enabled M33 DAC/Amplifier is a very high performance streaming amplifier with superb audiophile sound. As a BluOS-enabled component, the M33 can be combined with other players in a BluOS ecosystem of wirelessly networked music players throughout the home for an outstanding whole-home sound system. Employing the new
Purifi Eigentakt™ Hybrid Digital amplifier technology, the M33 follows in NAD's long tradition of identifying and developing cutting-edge amplifier technologies. With a minimum of 200W per channel on tap, the result is a lifelike performance, exemplified by ultra-low distortion and noise.
