Get 4 identical speakers, full range. Add a processor that supports circle surround (un-encoded) or similar (both Theta and Meridian have music surround processors that apply), turn off the center channel and the sub and you now have a sound system (on live recordings only) playing good ol' 16/44 CD's that will kill either of the two new formats --- and you get to use all of your existing music.
These technologies extract out of phase information and put it in the rear speakers. I am NOT talking about the artifical DSP processes that some suround recievers have.
This setup sounds better than any artificaly recorded surround music I have ever heard (DTS, AC3, DVD-A). And if you have great full range speakers, kills two channel audio. I don't know how many companies make processors that have this type of mode, but it sure is awesome.
VERY difficult to listen to 2 channel after hearing a top end implementaiton of this approach
