I've just recently made a change to my system (see the edited list in my previous post) - replacing a Parasound HCA-800 Mk II that had been giving me some trouble with a pair of Model 200 monoblocks. The M200's are driving my mains, and the Model 750 is handling the center and all four surrounds. So far it's been a great upgrade. The M200's match up with the 750 very nicely, and the back surrounds are much happier being on the 750.
