Say you have a 5.1 setup with good quality bookshelf speakers and a decent mid-range receiver like a Denon 2803 or Onkyo TX-SR601; something of that caliber. If you then add two mono-amps like the Outlaw 200's for the 2 front speakers, will that make those speakers sound a lot better? A little better? No difference? I'm thinking in terms of music, not HT. Whatever the answer is can someone explain the why of it? I keep reading how a better amp means better sound, especially with floorstanders, but I don't understand why. If we need specifics about the speakers let's use the Aperion Audio Intumus speakers for the example. Thanks.
