M33 BluOS® Streaming DAC Amplifier
In its simplest form, the M33 BluOS™ enabled DAC/amplifier is an ultra-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 audio system. With the employment of the new Purifi Eigentakt™ Hybrid Digital amplifier technology, the M33 follows NAD’s long-standing tradition in identifying and developing cutting-edge amplification technology. With a minimum of 200W per channel on tap, the result is lifelike performance, exemplified by ultra-low distortion and noise.
