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.

I do tend to have some concern for long term reliability of complex devices from NAD like the m33.  Otherwise it seems to be the bees knees for a reasonable price versus the competition for all that it does well. 
Lots of great class d besides those. I understand everyone has their personal preferences and different gear gels differently with others. but anyone who just totally disses Class D as not worthy categorically loses credibility with me instantly  and probably many  others as well who just happen to know better from experience and have better things to do than argue. 
I am pretty sure the NAD delivers a lot more power and current than those two which will make a big difference driving many modern day speakers to their max. 
Class D as commonly done today and OTL are apples/oranges at least technically and in terms of the system they might be used in to sound best. Class D will work well in place of OTL technically but likely still not sound the same. OTL has no chance of replacing Class D categorically.

So realistically you can compare the two and favor one over another but absolute statements in regards to superiority are probably subject to challenge at best.

Now I understand Atmasphere is working on a Class D amp. That would be interesting to see what he comes up with and how it compares both to other Class D amps and his own OTL amps.
I have 4 different Class D amps running in my house. They all sound dam good. Not to mention good value. As good as most anything in each’s class if not better. I have 4 because I started with one and went from there and have not looked back since. If Class D had not worked out for me I was ready to explore tube amps. Didn’t happen....no need. Class D is like the best of SS and tube amplification in one. It’s different. So no reason to expect everyone to love it just like everything else. But personally I think it is the way to go these days and will be even more so as time goes on. I have heard the Anthem but not the NAD. It sounded very good driving Klipsch Heresy IV, the best Heresy sound I have heard to date. Lots of technology in these new amps beyond merely Class D amplification. It’s a whole new world. Some will go there others not. Count me in! I will need another new amp sometime I expect.
Dsonic has a lot of measurements for their Class D amps posted on their website.  I was impressed!


These are good products but don’t change anything.  Some will listen to Class D and buy it and others still won’t.  So what?  That’s been true for quite awhile.  People can buy whatever they want or not.    Newer  technology  will always tend to get better over time.  Some will never buy in because they prefer something else.
