Difference in Using Mono-blocs with Maggie 20.7's

I agree with the above description. Jumping to the MC611 for instance would be a noticeable jump but not a "holy crap" moment. As long as you manage your expectations I think it would be a good jump, your Maggies will thank you.  

It's certainly worth a try those are as you know fairly power hungry speakers, and quite transparent. Some good advice above not to expect a sea change short of changing brands or going in a radically different direction. It should be asked what about the current setup do you think could be improved?

I did not necessarily mean Mc mono-blocks.  

stereo amp to mono bloc amps as a generality is essentially meaningless - what the to/from amps are, how they are designed and built, what specific stereo amp to what specific mono block pair is being considered ... those critical details are what matter

like asking, will i be better off going from a v6 engine in my car to a v8 model? well what v6? and what v8? what cars are we talking about? audi v6 to a buick v8? i’ll stick with the audi thank you very much ... you get my drift

Thanks peoples.  ghdprentice, (or anyone else) what would be your idea of a brand change that would produce a noticeable difference in terms of mono-blocs that are not McIntosh? and, why, of course.
