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.

Hey Tim,

I guess you are the resident fact checker! 🙊
I still own a Nad 390ccd all in one with Bluos board to use in summer time as can’t use my tube amps too hot. The Nad is detailed but boring/flat doesn’t make me want to listen to music for long time. I was excited to read newest tech Purifi. As you know all class D manufacturers say sounds like a Triode but with bass of solid state yeah right. Read some reviews and honestly same poop. Even a reviewer said great detail but thinner than real life no thanks!

Only thing that may have hope is GaN by ADG which adds in 2nd order.

Maybe in another 5 yrs class D may sound good!😮
Also, I reiterate unless you solely listen to analog master tapes in your home set up you need to add some bloom and warmth. I enjoy music from Tidal, Amazon and Spotify streaming.

i agree with this important point about making systems sound natural and real... something that most ’measurement geeks’ just fail to understand...

like they say, tube gear manufacturers haven’t been stealing deaf peoples’ money all these years
Kw6- listen to a NAD M33 and then honestly tell me it’s got great detail “but thinner than real life.”  That has not been my experience AT ALL!  Not even close.  All the reviews I have read (rightfully) praise it’s outstanding sound. I’m listening on decidedly mid-fi SVS Prime Pinnacle speakers, I’m not a “Golden-Ear” by any stretch, but I know when I hear great sound, and this thing has it.  Seriously considering getting some used Maggie’s and taking the system down to the more generously sized basement man cave, I’m sure they would sound amazing with the 33.
