stacking speakers?

Thanks everyone for the great input and advice.
I'll try out the differnt options and see what happens. O.k. Mezmo, I'll call you crazy. Just kidding. I did at one time have all the speakers hooked up to my HT system, Then I found the joy once again of 2-channel audio. In novice terms ( That's me, the novice) the music sounded better in 2-channel, then it did in surround sound. Having four front's and a center facing you, didn't sound any better then when I seperated the speaker's.
I would have placed the bookshelf's to the sides for a more complete surroud effect, but for one problem. My wife, and I qoute" your not going to be spreading your speakers all over the house making it look like a stereo store" end of qoute. :) Thanks again everyone.

Tsugury, sure I coud have stacked the speakers first, had problems, then started asking questions, but why? Isn't that the purpose of these forums, To find answers to our questions before hand. Up until two days ago the words "Sympathetic Resonances" wasn't even in my vocabulary. I now know what it refer's to, and have several option for fixing the problem if I still decide to go that route. Being a novice on a budget, I can't afford the trial and error route.
I've read to many threads of people doing that and blowing amps, speakers, or whole systems. If it's something that I know with my limited knowledge, that won't hurt anything, then I'll do it, but why not gatherig as much information possible about something before doing it for the best possible results. What would be the use of these forums if we don't ask questions?
