Although, I have been lurking on this site for quite a while, this is my first post. I am debating whether or not I would hear any improvment if I got some M200s. I currently have M&K 750 speakers (LCR) and M&K suround55-Tripoles (surrounds) powered by a Denon 3300 Amp (105W per channel). I am fairly satisfied with the sound, but the idea of mono blocks intrigues me. My main concern about the M200s is that they would be overkill for my speakers. Does any one have any experience running the M&Ks with M200s. The M200s are rated at 200W(8ohm) and 300W(4ohm) and my speakers are rated for a maximum of 200W(4ohm). I was thinking about starting with 2 or 3 M200s to power the fronts and center and continue to use the Denon for the surrounds for now. Eventually, I think I would get monoblocks all around, but again I am worried that this would be overkill?

Any help would be appretiated.
