Yup....I switched all my speaker wire to CAT5 plenum cable a couple of years ago...just opened up the wire ends...stripped the individual wires inside, and twisted all the stripped wires together for negative, and all the solid colored wires for positive.
I did one speaker at a time...and could definitely tell the difference....but, get the plenum coated CAT5...something about the dielectric property or shielding? I did this a year or two ago...can't remember all I read about it...but, it works.

Mind you the low end stuff (XP, 100 series, etc are all just normal cables), but the M-Series or 1000 series stuff.
Those cables are intense. The dielectric locks the individual pairs in place so that crosstalk and inductance are constant even if the cable is moved around or bent (sure it will change some, but not nearly as much as a cheaper cable will).
There is a lot of copper in those things, and everyone should agree that the more signal

I used to wonder about why you couldn't just do surround with 2 speakers, too. There are a few reasons, but I believe the primary one is how you pinpoint where sound is coming from - as your head moves around, your brain keeps track of what sounds get louder and softer and paints an aural picture based on that. Technologies have come out that create a surround stage with headphones or stereo speakers, but the illusion is destroyed as soon as you move your head.
That being said, I don't think this will catch on for a loooooong time. Even 7.1 sound, which came out a few years ago, isn't particularly widespead in home theater. The only people who will get this will be the easily suckered nutcases who blow their money on all kinds of HT gear for no reason. I absolutely cannot figure those people out.

Accurate 360 degree reproduction of sound requires at least 5 or 6 speakers at semi-equal dispertions around you, with one centered directly in front and preferably one directly behind, at equal distances from the listener.

That doesn't account for overhead or under-foot sound either, or the fact that seperate sub-woofers should be used for low-frequencies.
Personally speaking, I wish I had the additional center-stereo channels to bring dialog closer to the screen as done in some theatre recordings instead of my 5.1 system since my front stereos are quite far apart (to allow for proper seperation for all in the room). The center is useful here, but the additional inside-stereo speakers would help.
