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

Thanks for your opinion. Odd that you like the Rogue amp but the NAD is junk since they both have at their heart an amp designed by the same person. The Rogue is an earlier, older version and the NAD an improved design.

At least he bought them, listened to them and determined they are not for him. Unlike what you did on several other threads. 

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.

Yeah, twice, lol...

I don’t consider or buy audio components from manufacturers who won’t provide measurements. I screen products by their objective performance and if this data isn’t forthcoming, they are ignored. Those that publish and meet certain requirements are auditioned. That’s my approach. Many state of the art amp manufacturers publish their performance data. I look at such transparency as excellent customer service and appreciate companies that give the complete picture to their potential customers who value such data. Not everyone cares, which is their business. I do, and that’s mine.

I know, right?! Pretty amazing.

There is another class d amp coming out later this year for the diy crowd from Hypex that measures, so they say, even better than the Purifi. At this point though, I think we are entering the point of diminishing returns. Once it's below audibility, it's more an engineering exercise to keep improving the performance.
