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.
@raw33 Go to the Audiogon main page and search for KEF. There are more used KEF Blades on A’gon today than at anytime I can remember. An amazing speaker and you can get something like a Hegel integrated, such as Hegel 390 or 590 to drive those Blades to very satisfying levels of sound. You COULD be done with the music part of your system with just those 2 pieces for $18K - $28K.

I have spent several hours with the older Hegel 360 and the Blades. It was rather good, I attribute most of my happiness to the Blades. The KEF Reference 3 and 5 are very good, but for me, the Blades are really great and a big step above. Non-used Ref 3 and 5 are also on sale now at a surprisingly low price.

I do not know much about HT but you could get some KEF LS50’s for the rear, also on sale now. There must be a center speaker in the KEF lineup that could round out a very fine HT system.

This would not be a newbie system, but an end game system. At least for me.
Thank you for all your input. Although I am new to this game, I do plan on putting together a nice system, not a starter set and will upgrade as needed but certainly not in the near future.
