NAD Bows Digital Amp

As we stepped through the door at Lenbrook's joint PSB and NAD exhibit, PSB's Paul Barton said: "Have you heard the NAD digital amp?" The M2, winner of a CES Innovations 2010 award, was playing with PSB's floorstanding flagship Synchrony. It had a tight and crisp though not terribly warm sound compared to what we have heard the same speaker do with analog amps. (Incidentally, the Synchrony is one of our all-time favorite towers.) Power output 250 watts times two into either four or eight ohms. Price $5999. NAD also showed its new M56 Blu-ray player, which is fully up to date with BD-Live capability, and at $1999, it ought to be.
