Two months old in Mint condition. Original packaging included

For sale is an NAD M2 Master Series direct digital amplifier in very good cosmetic condition. Our tech has gone through and confirmed this piece is in perfect working order. The only repair that was done on the M2 was replacing the volume encoder. All functions are confirmed to be working correctly. Once called The worlds most advanced digital amplifier, this digital amp is a fantastic hub for both analog and digital sources. There are a handful of small blemishes that can be seen in the pictures, namely - a small scratch on the side of the unit, and some of the buttons silver finish has rubbed off.The NAD M2 Direct Digital Amplifier represents a new level of amplifier performance. Combining the ultra low distortion and noise levels of the finest linear Class A and Class AB amplifiers with the efficiency and streamlined signal path of the digital amplifier, the M2 is the first implementation of a new amplifier technology called Direct Digital Feedback. Co-developed with UK based Diodes Zetex Semiconductor, and using a unique implementation of their patented DDFA architecture, the M2 redefines what is possible with digital amplifier technology. The M2 Direct Digital Amplifier represents the culmination of a decade long NAD research project, capped by three years of intense development. The result fully justifies the investment. We believe that the M2 sets new benchmarks for both measured performance and subjective musical quality.- NADSPECS:2 X 250W Continuous Power at 8 and 4 Ohms>500W Dynamic Power, 22A Peak Current<0.004% THD 20Hz – 20kHz from 500mW to 250W>120dB Dynamic Range40uV Residual Noise>2000 Damping Factor at 50Hz+0/-0.5dB Frequency Response 20Hz – 20kHz, -3dB >85kHzChannel Separation >90dB @ 1kHz, >80dB @ 10kHzFEATURESDigital PowerDriveDigital Soft Clipping (switchable)5 Position Digital Impedance Compensation FilterRemote ControlCONNECTIVITYAnalogueA/D Conversion for Analogue InputsMulti-bit Delta/Sigma 24/192kHz0.0004% THD124dB S/N RatioHigh Resolution 120dB Digital AttenuatorDigitalInputs Digital SPDIF: AES/EBU, Coaxial X 2, Optical X 2Inputs Analogue: Balanced, Single EndedProcessor Loop: SPDIF Optical (Mac compatible)Rear Panel2 Sets of Speaker Binding Posts to facilitate Bi-wiringRS-232 serial data portIR Input12V Trigger Input and OutputGENERALStandby Consumption: 1WAmplifier Efficiency: 90%Power Requirements: 100 - 240V AC 50/60 HzUnit Dimension (W x H x D) Gross*: 435 x 148 x 502mmNet weight: 20.2kg Decibel Audio is a retail store and custom installation business in the Wicker Park neighborhood of Chicago.

NAD M2 DIGITAL AMPLIFIER (VERY RARE) No remote control, not original inner box (another M series) but will be well padded if posted). 250 W per channel, weight 20kg. Very rare because NAD did not keep it in production long despite the reviews below, as apparently they did not make a profit on it, and replaced it with cheaper and inferior implementations. The Absolute Sound - December 2009 Despite costing one-tenth as much as my reference system (all the components of which are outstanding), the M2 was extremely engaging musically. Overall, I preferred the reference system, but not by as much as the price disparity would suggest. I usually wouldnt judge a $6000 product against one costing more than $50k, but the M2s outstanding performance in many areas invited the comparison. NADs M2 is a triumph on many levels, not the least of which is that it points toward a new direction in amplifier design and system architecture. I predict that years from now audiophiles will look back on the M2 as the progenitor of the next generation of audio. Stereophile - March 2010 The integration of a D/A processor and power amplifier into a single chassis eliminates the need for an actual preamplifier, instead substituting a digital-domain volume control and switching. Of course, the M2 does have two analog inputs, but as these are digitized ahead of the volume control, it doesnt affect the picture I have painted of the M2 as a paradigm-breaking component. Once I had changed my system approach, the NAD M2 provided many nights of extended listening, with one album leading to just one more. And one more. While the M2 is relatively large and heavy for a class-D amplifier, runs warmer than you might expect, and is not inexpensive, when fed high-quality PCM data it offers sound quality that competes with that of the best conventional amplifiers. Given my long-term skepticism about the sonic benefits of PWM amplifiers, that was not what I was expecting. NADs Masters Series M2 is a winner all the way. Hi-Fi News June 2010 - Nad M2 (5000) The M2 is the first digital amplifier I have listened to, but the best integrated amplifier period. A revelation in almost every audio respect, its accuracy, dynamics, instrumental separation and detail resolution set new standards at the price. Revealing epiphanal micro-detailing and recording rubbish in equal measure, it is as ruthless as it is stunning. NAD can be proud of this digital engineering triumph.
