NAD M2 Master Series Direct Digital Amplifier w/ Remote & Manual - Silver Finish - 250 WPC

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 world's 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." - NAD
