In the two times I have put together an audio system I have really over spent for what i really needed.
Back in 1989 when I work for an Audio video company and was able to buy audio equipment at wholesale, I bought a really cool looking pair of pyramid shaped speakers (brand?) with the tweeters balls on top (classical music type speakers), spent $1400, a few month later I figured I could have spent $800 (or less) for some JBLs and been happier (better base sound).
A few months back I purchase Infinity Beta 40s, 20s, C360 at the close out prices for $780, now I've figured out I could have just gotten the Infinity Primus Theater Package 5.0 for $310, which have been fine for my little apartment.
So unless you have some really good reason to spend more money, just go with the cheapest.
You can always sell off the stuff in the future if you get the upgrade bug.
