Ok After reading speaker reviews for about the last month I know I really screwed up by buying the bose acoustimass 16 series series 2 speakers for my denon 3806 receiver about a year ago....since then I just sold my denon and bought yamaha v3900 thinking I would get better sound from a different receiver and im still disapointed with the flat sounding bose speakers!!....I need speakers that will really fill up my room with full sounds when listening to music and when watching movies give you that wow effect!!...Ive read many reviews and havent been able to pinpoint some serious speakers that would be on the same level with my receiever...and even worse im located in an area that doesnt have any high end audio stores around I can go to and sample equipment!!...I wanted to spend in general about 2k on speakers but they have to be some amazing sounding speakers with that wow effect!!....any recommendations and advice is greatly appreciated!!!! thanks!!
Since you've been listening to Bose almost anything is an upgrade.

Which is a nice thing
Surrounds aren't super important. So just stick with them boses
Then you could spend the 2k on subs and fronts.
I suggest you get 1k towers and spend 1k on subs
Phantom the center and use the Bose speakers as surrounds and you will have a very nice setup.
If you can sell the Bose set for a few hundred you could change to KEF eggs or something similar for surrounds.
