Depending on what music you like, you might want to stick with HSU, and get their HB-1s. I bought some HB-1's and loved them so much I went out and did something crazy: I bought two HC-1s and am using them vertically as bookshelfs. I wanted the same sound, except more so! This system certainly isn't for everyone but for me it is absolutely killer!
You may also want to consider the Emotiva ERM-1, if your amp can take the 4 ohm load. They are on sale right now for $150 a piece, down from $230, and if you order three you get free shipping. I have been curious about the emotiva speakers, and probably would have went for this deal if I had a little extra cash laying around.
