Ever so often a product enters our lab that absolutely blows us away and redefines a category. The NAD M23 is such a product as you can see in my test report. This type of Class D design marks the end of an era of inefficient linear amplifiers.
The NAD M23 is a 200wpc stereo amp that utilizes the SOTA Class D Purifi 1ET400A reference design to push the envelope of performance and efficiency. Weighing just a tad over 21lbs, this amp can double down with halving load impedance and be bridged to get 1kwatt of power as a monoblock. What is most impressive about this amp is the extremely low noise and distortion performance that forced us to redesign our test fixture to more accurately measure. Is this the best measuring amp in Audioholics 23+ year history of reviewing AV gear?
