Internet direct is going to give you your best value...
Check out SVS, HSU, and Rythmic for your subwoofers
then Ascend Acoustics, EMP, HSU, ect. for your speakers... Rite now there are a lot of good deals on Focal towers and bookshelfs at musicdirect.com and accessories4less.com, I like the sound of the ascend acoustics 340se's but they are not finished as well as a lot of other brands..
Also if them "best buy" speakers tortured you, you may want to look at the Wharfedale Diamond series, they are much warmer and not as aggressive as most of the stuff you hear in stores....
good luck and welcome...
