Brian, pretty much the same answer, and note that this isn't simply my "opinion", but rests on basic principles of how amplifiers work plus the results of controlled blind listening tests which have failed to show the differences sometimes claimed. In this latter connection, if you haven't studied the results of the classic amplifier blind listening test in
Stereo Review you may find it enlightening. These results still stand unchallenged(i.e., unchallenged by contrary solid evidence, not just stubborn disagreement)despite later investigations.
Among the interesting points in the tests are the comments which are at the very end of the article showing the clear differences in "sound-stage", etc. which were described in open listening before the blind sessions began, but which disappeared when the name plates and price tags also disappeared. Especially interesting was the comment of the "believer" at the end of the tests(but before being shown his score)who apparently scored 7/16 on the Hafler/Futterman session 3, but still was describing the differences that he'd heard. Incidentally, the $12,000 pair of Futterman tube amplifiers, which apparently didn't have a flawed "tube sound" and which which were indistinguishable from the $220 Pioneer receiver in results, for some reason were off the market about a year later.
So no, the mono blocks have no capability to improve the sound in some mysterious fashion if the sound levels are carefully matched.
