NAD Masters M28 Seven-Channel Amp Uses Purifi’s Eigentakt Technology

NAD Electronics says its new Masters Series M28 seven-channel high-performance amplifier is the first multi-channel amplifier to use Purifi’s Eigentakt self-clocking amplifier technology.

First used in the NAD M33 Masters Series BluOS Streaming DAC Amplifier, the Eigentakt amplifier is manufactured by NAD under license from Purifi, a Danish technology company that brought together several of the industry’s leading engineers.

Purifi says it has found many seemingly small non-linearities that, when corrected, can make a “dramatic difference in the overall sound.” Thanks to advanced technology, well thought-out PCB layouts, and advanced mathematical modelling, the M28 provides less noise and lower distortion.

In common with previous generations of NAD HybridDigital technology, but unlike most Class D amplifier designs, the M28 is able to easily handle long cable runs but is impervious to the loudspeaker load it is presented with, maintaining the same wide and even bandwidth response irrespective of the speaker’s impedance and at the same time providing high current capability, says NAD. On tap is 200W into 8 Ohms of continuous power for all channels driven at the same time and 560W of dynamic power into 4 Ohms.

“NAD has always been known for great sounding amplifiers that punch way above their weight and the M28 does this at a reference level and then some” says Cas Oostvogel, NAD’s Product Manager. “Using the Purifi Eigentakt technology, the M28 delivers massive amounts of power with sound quality that has to be experienced to fully appreciate. Even better, NAD engineers have managed to deliver all this performance at a cost less than traditional technology.”

The M28 accepts both single-ended RCA and balanced XLR inputs, with high-quality binding posts that provide solid speaker connections. The unit’s design matches that of the NAD Masters Series M17 V2i preamp/processor.

The NAD M28 amplifier will begin shipping in Canada this month through Lenbrook International for an MSRP of $6,999.
