The NAD M33 will cancel your complaints about Class D


There are many reasons to like one type of sound over another. Even among what are considered very good amplifiers there’s a broad range of tastes and preferences among audiophiles. Just ask a SET aficionado!

However, no class is more maligned, inappropriately, than Class D. To hear some regulars tell it, Class D sound will thin your blood, make your teeth fall out and ruin your enjoyment of just about everything because it sounds so (fill in a lot of tropes from the 1980’s here).

I’ve been listening to NAD’s prior collaboration with Bruno Putzy and I can tell with some confidence that none of those tired old tropes apply. For reasons related much more to tonal balance than anything else, I’m sticking with Class A/B in my main system, but with the introduction of the next gen Anthem AVR receivers and the NAD M33 I may be making the switch back to class D.

You don’t have to like the M33 or the Anthem’s but can we at least agree that it’s time to retire the old guard of reasons not to buy Class D? Lets lay those poor phantoms to rest.

Erik, my reply was deleted by mods because they’ve figured out that any conversation that runs counter to the prevailing orthodoxies here is bad for business.


My stated SINAD numbers were taken from the full ASR M33 write up, which I linked above. I was comparing unweighted measurements versus the PuriFi reference design which has already been exhaustively covered by ASR. Mid 90’s SINAD is about 25db more noise than the reference design, so not anything to write home about. 

Think I’m done posting here, it’s not fun being moderated over nothing. 
There are other purifi amps that measure better as well as Ncore amps. I think the main attraction of the M33 is being an "all in one" device. I notice NAD doesn't show specs for 2 Ohm, not sure if they limited their implementation as other companies show 8-4-2 Ohm specs.
