NAD Unveils M2 Direct Digital Amplifier
Audio components supplier NAD Electronics has partnered with the U.K.-based semiconductor company Zetex to develop what NAD is calling a “high-resolution, true digital amplifier.”
The M2, the new flagship in NAD’s high-end Masters Series, is the product of what NAD director of product development Greg Stidsen says was the culmination of a 10-year-long research project with the goal of achieving a new performance level in digital amplification. “The criteria we had set for ourselves was that it had to be at least as good as our best analog amps’ performance. We had not been happy with Class D amplifiers’ measurements, or their ‘listening.’” He points out that most Class D amps are spec’ed at 10 percent distortion while the M2 is spec’ed at 0.004 percent distortion.
The M2 incorporates Zetex Class Z direct digital feedback (DDFA) technology, which the companies say imparts both efficiency and, according to Stidsen, the “audio performance our customers expect.” Zetex’s approach performs all control functions in the digital domain. The result, they say, is low distortion and better linearity.
“This product is ideal for NAD – it specializes us and truly sets us apart from the mass market,” says Stidsen, who adds that the technology will be used smaller, less expensive NAD models in the future.
The M2 is to be available in summer at $5,999.
