Ok,... 'cause there is a BIG difference between a $3000 pr. of speakers and a $3000 set of 7.1 speakers ;-)
I'd suggest going with a 5.1 set (then later add a couple of speakers for the 7.1)
Look at / listen to offerings from the likes of RBH Sound, Paradigm, Totem, Monitor Audio, B&W, etc. etc.,.... also do not dis-count the less expensive JBL, Infinity, Polk, Klipsch and other major brands. You may find you like the sound of them better. Get out and listen to as many as you can and pick what YOU think sounds best (even if they cost less than your budget)
