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 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,..
Blades - haven’t heard them, but I entered high end by spending 80% of my budget on Magneplanar Tympani 1a speakers in 1973. The first speaker to be awarded Stereophile’s Class A.

System didn’t quite sound like all mega-buck, but it was 90% of the way there. So if the Blades blow you away like the Tympani 1a’s blew me away, I say put them on the list and skimp everything else. Other stuff can be brought up to standard one significant birthday at a time. And that very much includes cables.

If you like the sound of Blades, also consider electrostatics and Magnepans. I’m a multiple-Quad ESL man, myself, and I built the electronics to conform to them.
I am not a big fan of B&W speakers.  Where's the base.  However, if you buy a pair of REL S3 SHO subwoofers that would fill in the lower extension.

I would look at ARCAM.  I have their AVR550.  However, I wish I could have afforded to spend $3,000 more on their AVR850.  It blew the doors off the MacIntosh.  I like their G amplification technology, as their first 50 watts is pure A.  Don't know why people feel ARCAM is not audiophile.  They are missing out that's for sure.  The only amplifier I like for the money is Parasound.  They sound really good and I believe they now have a multi-channel processor.
