NAD M23 Stereo Amplifier: Best Amp Ever Bench Tested?!?

I don't think NAD uses Purifi modules, they license the technology and build their own. 

It's usually DACs that test the limits of the Audio Precision analyzers. I've never heard NAD purifi amps but I have heard the Purifi modules as well as different hypex and Pascal implementations. They've all sounded good to me as in I couldn't attribute a sound to them but then again I don't have bat ears.

I don’t use a tube preamp with class D amps, kind of defeats the point of getting class D. I don’t want a damn tube in a DAC either. If you want tubes then buy tube amps. 

Way to keep it classy

Thanks

I do not think that was a compliment.

I'm wounded !!  Is this a dagger which I see before me ! 

Tubes on buffer stages don’t amplify the signal, so to say tubes give class d a nice tuby sound by sticking these contraptions on class d modules is just marketing speak.

Benchmark is the Benchmark but I wish it had more power. I doubt anyone could tell the class G  Benchmark from a well designed class D hypex or purifi. 

Tubes aren't more "linear" than a JFET but they will keep you warmer in the winter and survive a nuclear attack.
