T+A Class D Amps ( M200 or A200)?

Ooph, they’re both Eigentakt amps? And you’re hoping the monoblocks together with a better power supply and implementation will make an appreciable difference? Your ears are better than mine my friend. Spec wise, you may be right. But that sounds like a nearly lateral move to me (for both rooms). Don’t get me wrong, I love the Purufi Eigentakt amp. And I really doubt any GaNFET can best it (especially considering their price at even lower wattages) . Still a trial for the cost of shipping? Why not give it a try.

Let us know,

Thanks, @ericrhodes1 

you have articulated the reasons for my hesitation pretty well. Will the T+A sound better than the M33 in any material way if i am not upgrading anything else?  For a lot less $ i could trade in the c399 for a new m33 v2 to be used for the Epicons and put the OG m33 with the Revel 226Bes. 

Yeah well, it sure won't cost you anything to insert your m33 into the Revel room right now. Start there. But I'm worried that what you find lacking may just be the characteristics of D amps in general. Perhaps you could consider improving the dac instead. 

The M33 is no slouch so from that perspective it’s not too surprising you’re pretty happy overall with what you’re hearing.  But there’s a big difference between liking the sound being truly moved and captivated by it, and IME that’s the next level and what can be achieved with higher-end components.  It can be easy to be lulled into liking what you hear until you hear what’s possible with something much better, and then you’re not so happy anymore.  Just purely as an example, inserting something like this Gryphon Diablo integrated into your system would very likely be transformative on every level.

But at this level it becomes highly personal and dependent on individual tastes/system synergy and only you can determine which components deliver the sound improvements you’re looking for.  I’m just stating the obvious that there is a much higher level out there and you should do some more research as to which components likely deliver the specific sound characteristics/improvements you’re looking for.  I’d also emphasize that everything matters a lot so plan on a better streamer, DAC, preamp/amp, and probably even cables.  What’s your budget, and are you looking for new or used?  Knowing that and having an idea of what you’re looking for you’ll at least get some good thoughts/ideas here to look into.  All that said, I don’t think throwing $$$ at the T+A amp is a good idea at this point as it’d be a crapshoot until you do more research as to what else is out there.  I would highly recommend traveling to some dealers/shows if at all possible to go hear for yourself and ideally demo components in your system.  Anyway, just my $0.02 FWIW.

All good points, thank you guys.

and @soix, you are right I would be pretty much throwing darts in a very dimly lit room at this point. I should figure out a way to go and hear more gear before i start buying stuff (even if it is returnable). The hassle factor in return shipping decreases the incentive to be strict about whether the item really is a meaningful upgrade. (That, plus placebo effect and confirmation bias.)
