Dan, the fact is, you can get reasonably full frequency response and a stellar soundstage with 2 speakers, so long as they are exceptional speakers and are positioned and powered properly. This means more than just the most brute force power available, but quality power and electronics all around. My main speakers can produce sound seeming to come from any specific location in the room all on their own, if that is what the engineer intended. No amount of piling the room full of speakers and amps will ever accomplish that.
