NAD lancerer forstærker med unik dansk forstærker-teknologi

NAD præsenterer high-end syv-kanals forstærker, der integrerer den såkaldte Eigentakt forstærker-teknologi, som er udviklet af det danske firma Purifi (in english).

NAD Electronics has unveiled another new and unique Masters Series product. The M28, a seven-channel, high-performance amplifier that can serve as a powerful engine for a state-of-the-art multi-channel system for music or home theatre.

The reference amplifier is the first multi-channel amplifier to utilize the Eigentakt (self-clocking) amplifier technology, manufactured by NAD under license from Purifi, a Danish technology company that brought together several of the industry’s leading Class-D audio-engineers.

While there are many good sounding amplifiers on the market today, Purifi has taken a fresh look at every aspect of amplifier performance and found many seemingly small non-linearities that, when corrected, can make a dramatic difference in the overall sound.

Advanced technology, well-thought-out PCB layouts and advanced mathematical modelling solved the last remaining limitations of audio amplifiers. The measured result is less noise and lower distortion, but the audible result is something more. The detail and transparency of the sound provide new levels of refinement at any volume level.

In common with previous generations of NAD HybridDigital technology, but unlike most Class D amplifier designs, the M28 is not only 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. 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.

Eigentakt technology is very analogue-like in behaviour in the unlikely event the amplifier is driven into clipping. Whereas many Class D designs can become unstable, Eigentakt behaves in a way like the benign way of clipping with instant recovery of well-executed traditional Class A/B amplifiers.

- 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.
