αυτή την κριτική του σετ προ-τελικού της NAD M12/M22, γράφει μεταξύ άλλων (μετά από διάφορα εγκώμια της φυσικότητας και της δύναμης του αποτελέσματος):
Those familiar with my reviews might be surprised that I am praising a Hypex PWM amplifier, even though I often argue that this technology is wasted on me. So far, I've never been able to get used to PWM except in subwoofers. But improvements have been made over time, and the same sort of Hypex Ncore modules found in the Grimm Audio active speakers can be found inside the M22. Many other brands just adapt the Hypex technique, fit a power supply and put the result on the market. NAD is a little bit different. Tried and tested techniques from its own amplifiers are combined with Ncore to turn a technical solution into a musically capable one. [...]
Accustomed as I am to an all analogue class A Audia amplifier combination ranking the NAD M12 and M22 is pretty easy, by comparison they are clear in nature, but not in a nasty way. For example, the opposite of the Audia’s sound is Devialet with its ADH solution which is closer to the technically perfect end of the spectrum. Don't get me wrong, Devialet does great things and those who have heard their SAM system will undoubtedly have been just as impressed as me. Yet I cannot imagine myself switching from old fashioned class A(B) to any kind of PWM, not even when it bares the Devialet logo. I had an M2 integrated for several years but in the end it had to go, so why embrace the M22? Maybe because of the clean sound, the musicality, the boundless deep bass or the intense pleasure of looking deep into the recording process.
Συμπέρασμα: η υλοποίηση, όπως σε όλα τα πράγματα, μετράει πάρα πολύ, πολύ περισσότερο από τη "φύση" της τεχνολογίας --τουλάχιστον τώρα που αυτή έχει ωριμάσει αρκετά.
