NAD Bows Stereo Hybrid Power Amplifier With Purifi Technology

NAD bowed a digital stereo power amplifier with Purifi Eigentakt technology, a “once-in-a-decade” innovation first introduced in the M33 BluOS streaming amp. The 200-watt-per-channel M23 ($3,499), due this month, has switch-mode power supplies and Class D output stages that are linear over a wide bandwidth and provide consistent performance into all speaker loads, the company said Wednesday.
