confused and don't know what to do

We would like to buy a nice audio system and also have this double as a surround sound but listening to music is the priority. We have listened to many speakers but have settled on the B&W 804's. Now the challenge is to select a receiver and all the other accompaniments we require. We have a little challenge in that our home is a condo and the outside wall is all glass. The space is combined kitchen, living room, and dining room all open with hardwood floors and hard tile on the walls of the kitchen and a lot of granite counter tops. It seems that every where we go, the recommendations are different depending on what the store is selling and of course, the sales people would like us to buy the most expensive. What would give great sound without going crazy. We are thinking about 2 tribe sub woofers and space is limited and an in wall center B&W speaker but we don't know what we are doing and don't want to throw our money away. Help! Too many choices and we don't have enough knowledge. Thank you so much.

Give audiotroy a break, he is just trying to make a living...  He does give good advise in my opinion, since I have researched some of his quotations. I believe there is nothing wrong in trying to sell a product that he believes and has confirmed its a good product. Some vendors do have good intentions plus I have seen him recommend product that he does not sell.
I got to hear a home theater a few weeks ago that doubled as a 2 channel set-up.  He is using 7 Dunlavys, a bunch of mirage (?) speakers on top of the dunlavys for atmos (?).  Anyhow, it was quite the set-up.  3 15” subs and an enormous screen.  He says retail on the set-up is $300k.  He has like $15k in cables.  His set-up was really cool and music sounded fantastic (SC IV).  When he turned on need for speed and let me see the theater aspect, I was really impressed.  It was right up there with the most dynamic imax theaters I have been to, if not better.  It was pretty incredible.  Regardless, you can have both apparently.   Theater and music...
