Difference in Using Mono-blocs with Maggie 20.7's

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.

You would really like Parasound JC1s. 

My next big improvement to my system will be to invest in speakers in about the $50 to $60K range.  And, I would definitely want mono-blocs for them.  My estimate of range of cost came from Paul McGowan's book on sounds systems.  He suggests 40 to 50% of the total value of your system be invested in speakers.  I have found him to be a reliable source of information.   

op

sounds like you are a bit all over the place

you have truly great speakers in the maggie 20.7 - if you are committed to them we can suggest better amps than your mcintosh, be they stereo amps vs monos (this particular distinction being a minor one in my view)

but if you’re going to buy new speakers, discussing amps is a waste of time until you have determined what is your future speaker choice

in all this, there is also no discussion at all on what you are seeking as the nature of sonic improvement you seek, your room, your choices of music, your sources etc etc... problems are solved when the problem definition is stated precisely and cogently... otherwise it is just burning $ while shooting in the dark
