NAD Masters M23 Stereo Power Amplifier
$3,749.00
Building on NAD’s long tradition of identifying and developing cutting-edge amplification technology, the M23 HybridDigital Stereo Power Amplifier features Purifi Audio’s Eigentakt™ design, a once-in-a-decade innovation that virtually eliminates harmonic and intermodulation distortion. Noise is inaudible, for a completely black background and exquisite micro-detail. Conservatively rated at 2x200W continuous into 8 ohms and 2x380W into 4 ohms, the M23 can deliver live performance levels through any loudspeaker. With its unique combination of features, performance, and value, the M23 represents the new benchmark for the stereo power amplifier.
