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.

If you decide on the KEF’s, I recommend using electronics that are on the warm side such as Mcintosh, Pass Labs, etc.  These speakers can be a bit bright at times and create listening fatigue, but they are great for home theatre in my opinion. You should also check out some horns like the Klipsch La Scala AL5 or Cornwall IV, Volti Audio stuff,  etc., this is like listening to live music in the comfort of your home. I recommend looking at reviewers on line such as Steve Guttenberg and others and this will help a bit, but audition, audition, audition..
Keep in mind what you like others might not and there is a whole industry to explore.

i have 2 pairs of b&w’s:  686( 2005 bookshelves)and dm 580 (90’s floorstanding) and tried them at home with arcam delta 60 integrated ,arcam delta 120 power amp (with some ss and tube preamps),nad c352 (given as a present to a friend), an old rotel receiver (traded for a wireworld rca cable)and a jvc receiver(given as a present to another friend). arcam and b&w always work the best since arcam is warm and realistic so it’s never dull (b&W and nad or jvc)or too bright (b&w and rotel)which are the dangers with b&w speakers .

If you decide to split your music from h theatre look into you can go Parasound for amplification and a good pro. Another good h theatre setup is NAD, with either of these you don’t have to break the bank and they are good.
I think Classe audio is back in business. Sound United took the Classe line from B&W and according to all my research they are very good for both. They attended the Munich audio show just this past year to introduce their new Delta line. Classe has a very good reputation and I really think you should look them up and read their reviews. 
Sorry, it seems I bombarding you with pieces at a time but I am writing things as they come to,..
