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 was running PS Audio M700's (L,C,R) and a S300 (surrounds). I loved their sound. Had to trade them in for a BAT VK50-SE Preamp because my requirements changed. Also used the Orchard Audio STARKRIMSON Amps that had had even better sound than the PS Audio M Series' WRT to upper Bass/Midrange/Highs. But they kept blowing up on me (long story). So I'm back to a pair McIntosh MC50's  for the Upper Bass/Midrange/Tweeter section on a pair of KEF 105/3's while a ICE Power 1000AS Class D Amplifier (1000W peak @4ohms) drives the dual 8" Cavity Coupled Woofers.
I found this post by seanheis1 from another class D thread to be very interesting and relevant:

Fact is the times have changed in audio. Digital is blossoming with tech that combines dac, amp, preamp, room correction etc.. all into one or two boxes keeping the signal all digital up until the point the signal is sent to the speaker.

Read all the recent reviews of my Lyngdorf 2170 or the Exogal Comet and Ion amp. The future is here right now.
Grannyring - there really hasn't been much discussion on this thread about digital Class D...mostly analog Class D using modules from Hypex and Ice...a few from Pascal & Abletec. Your Lyngdorf appears to use the TI Equibit technology, which combines amp & DSP. Very interesting stuff.     http://www.futurlec.com/News/TI/AudioSolution.shtml 
Have the M33 and M50.2 hooked together, using Spatial Audio M3 Turbo S.
Best sound I've ever had in my home, bar none. And I've had some of the very finest gear on the planet.
So, say what you will but I wouldn't trade this for anything at the moment.
Whatever they did, they did it right.

so tell us, as we are curious - what are the other pieces of equipment/systems you have had that are summarily eclipsed by what you mention (nad/spatial m3t)?

not challenging your assertion per se -- but would be useful to know, so many of us on this board can do a little benchmarking on what gear is 'finest on planet' 

thanks in advance...
Lol, of course this hobby is very subjective and everyone hears things differently, that post is just my opinion based on my ears.I started this hobby in 1976, my first system was McIntosh tubes and Klipshorns. I've had McIntosh in my house ever since, but I've also had Audio Research tube preamps and amps, various models. I've had Von Schweikert speakers, again several different models, Magnepans, and Quad. This is my first Class D venture, never heard one before the M33. The only thing I remember being as holographic and with such a detailed image and big soundstage has been some tube gear I had, Chinese Ming Da, big 805 radio tubes and Von Schweikert VR9, the Audio Research gear was very close. I've owned many other brands of solid state and tube gear, really can't think of a solid state system that was this good.
If the M33 lacks depth to some people, it certainly doesn't here, maybe they need to look at other parts of their system or room. With the Spatial Audio speakers the soundstage is huge in width and depth and very accurate imaging. I'm very happy with what I'm hearing and I only have 2 boxes sitting on my shelf now. One balanced digital cable between the 2 and a set of speaker cables, that's it. I needed to downsize and this fits the bill. Gotta Love minimalism.  And another thing, for $9k I think its a bargain.
