This is the top-of-the-line NAD Masters Series M25 Amp with 160-watts x 7 channels of massive power to meet the demands of a serious home theater or listening room.
This unit is in pristine condition both physically and functionally! Everything works beautifully and there is not a single scratch or blemish to be found. This was used in our Home Theater and has always been kept in a cooled, low-dust, smoke-free equipment room.
We recently upgraded to an amp with 11 channels, which is why we are selling this.
---Manufacture's Description below---
The M25 contains 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. NAD employs a unique electronic ground isolation circuit to prevent ground loop noise, a common problem with many complex multi-channel systems.
Intelligent features ensure clean, dynamic sound and 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. The M25 also incorporates NAD's acclaimed switchable "Soft Clipping®" circuit, which gently transforms the audio waveform as the point of clipping distortion approaches to keep the sound clean and your speakers protected.
The M25 can deliver its full rated power continuously for hours on end. Custom designed heat sinks and variable-speed fans work to keep the M25 running cool under the most severe conditions. A unique circuit that tracks signal level actually shuts down the fans during quiet passages.
The M25 utilizes NAD's proven Holmgren Toroidal transformer design to create a power supply that offers well regulated voltage, massive current and low noise. Multiple high-grade capacitors ensure a clean DC voltage supply for very low noise and explosive dynamics. Copper buss bars are used exclusively throughout for power delivery and grounding.
Buffered low-impedance level controls allow system fine tuning without the distortion typical of most level control circuits. Custom-designed, gold-plated speaker binding posts offer multiple connector options, while maintaining a large, corrosion-free, low-impedance contact area.
