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.
Difference in Using Mono-blocs with Maggie 20.7's
Peoples: I've had Maggie 20.7's for about two years. I like them. I have a McIntosh MC462 amp that generates 450 watts pc and does a good job. However I'm considering going to mono-blocs in search of an improvement in sound quality. What is the likelihood of that being the case? I've read much over time about how amp's can make such a difference in sound quality.
Anyone out there make this change, and if so to what result? Otherwise any other useful feedback is welcome.
