Class D is just Dandy!

Heat and weight are not a concern for me, either. But I can see where those 2 things might be appealing for some. I won't lie in that I am struggling some to be really attracted to Class D for now. The technology seems to be changing rapidly whereas Class A/B at the least is mature. Same reason why in general I do not prefer paying for a DAC built in to the preamp unless the maker has a way for future upgrades. Dropping $5K or $11K for a pair of monoblock Class D amps only to see a much improved amp board emerge in 2 years would hurt my financial feelings. My spousal unit is very good with accepting my expensive hobbies to  a point. Course if that $5K Class D amp already produces sound quality I find superior to every Class A/B amp I can find in the same price category then it may well work. But am giving consideration to some SST equipment (Son of Ampzilla 2 and Theobe II) as well which will not cost as much as some of the Class D options I am looking into! Course maybe I should just stay with my current setup... it is good and is now free :)

@jdavis37 Not all Class D manufacturers use third-party amplifier modules. Check of Digital Amplifier Company. He designs his own Class D amps, or at least that's what he says (see website.) I own a pair on his Maraschinos and I love 'em. I also have some experience with other brands you mentioned. But I'd rather not speak of that here. PM me if you want more information. And I am not affiliated with, nor compensated by, Digital Amplifier Company...just wanted to get that said.

Thanks MDE.. gives me something else to read about. His approach seems a little different and his units carry a bit of weight to them (Makes class A/B people like me feel more comfortable!). I'll PM you fo rthe other info!

MDE.. I'm not an audiogon regular so PMng seems to be escaping my abilities! Feel free to send from your end :)

I did try a pair of bel canto ref 500m monos a couple of years ago but for reasons I think mostly associated with the other gear I quickly moved on!

However in my ht rig the move to class d amp was a massive step forward in every way.
Replaced my Emotiva amps with a tiny single nuforce power amp making a claimed 150w x8, only using 7 channels for my 7.1 system.
The emotivas claimed 300w x2 and 250 x5, not quite sure where they were hiding those horses as the nuforce creamed them in every aspect.
dynamics, action, dialogue, sheer volume were vastly increased with the nuforce.
and now I have one tiny little box which has replaced two behemoth amps that were sucking juice and pumping heat.

I will at some stage give a pair of mono class d amps a whirl in my main rig again I am very sure!
