NAD Masters Series M25 7-Channel Amplifier

The THX Ultra 2 certified M25 is rated at 160-watts per channel with a rated distortion of 0.03 (proclaimed All Channels Driven (ACD) simultaneously, from 20Hz to 20kHz.)

NAD claims the M25 can deliver its full-rated power, free from distortion for hours on end. Custom designed heat sinks and temperature regulated, variable speed cooling fans work to keep the M25 running cool under the most severe operating conditions.

The M25 is actually made up of seven individual mono block amplifiers with each channel using a balanced junction FET input stage to eliminate cross-talk, resulting in exceptionally low levels of noise and distortion. Additionally, NAD employs a unique electronic ground isolation circuit to prevent ground loop noise in the system-a common problem with many complex multi-channel systems.

NAD's proprietary PowerDrive circuitry measures each channel's dynamic impedance individually and computes the optimum power supply voltage required to drive the output stage for maximum power and efficiency.M25 7-Channel Amplifier Features

Subjective Impressions:
> All of the Masters Series products on display were beautifully crafted and commanded respect. It was obvious by the large power supply under the hood and tons of heatsink area that this amplifier is a true powerhouse.
