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.

Forget about how a speaker sounds at Best Buy. You need to try (borrow from stores or friends) a speaker to hear in your own listening environment, which as you describe, sounds like a challenge. The room is the biggest variable. Figure out where the speakers are going to go. Do they need to go up against a wall? Certain speakers, like Larsen's, are ideal for wall placement. Most speakers benefit from being out in the room and the room you describe, btw, does not sound like a good candidate for home theater, so can definitely save money by sticking to 2-channel which is adequate for most video and ideal for music. Indeed you should start "backwards": buy a speaker that will drive your room, then an amp that will drive your speakers and with whatever money is left buy the best front end components you can. There are definitely differences between front end components but nothing like the differences between speakers in real life rooms. I've owned quite a few great speakers that just didn't work in my room. Don't make a mistake like that!
Since you are in an open-space condo, space (footprint) might be a consideration. My wife and I are facing the same issue. I settled on a BlueSound PowerNode 2i, which includes a streamer and integrated amp.  Your selected speakers will certainly work with them (I have ELAC Debut 6.2s that are great).  Includes an HDMI port for the TV. And you can hook up a subwoofer and Bluetooth speakers.    With all that reflective material in your condo you might not even miss the extra three speakers.  
Some really good advice here, as well as some monster systems. Let me lend my experience; I’m sure some will not get past my first sentence or two - I hope the OP does! :) I’m envisioning your condo with a lot of "life" going on: kitchen, dining, living, etc. AND - you have a significant other IIRC. This system can’t be a mess of wires or remotes or components (did anyone ask what you play? Stream? Vinyl? Physical media? I’ll assume you stream...) I had the same issues. I wanted GREAT sound and intelligibility from movies and TV...and I wanted GREAT sound from music. What I did: I listened to as many top-line soundbars, then purchased a Martin Logan ’Vision’ bar; I’m sure there are even better ones now. I was going to add a sub, but have not yet. For music, a pair of wonderful North Creek standmount speakers designed for near wall placement (NC is no longer in business, but my point is some NICE stand mounts or towers, ultimately should be purchased with consideration for placement). If I were buying components today, I would purchase a fine integrated from Jeff Rowland, Rogue, Moon, Bel Canto, McIntosh, etc etc. Go tube if you want! Add a (matching?) streamer. DONE.
What I just described is a one or two box solution; speakers for music, and a sound bar which is completely dedicated to you video system. (I use a Roku 4K with mine, mounted behind TV. Very clean)
The advantages of a fine soundbar have blown me away after living with it for 3 years: absolute simplicity with very superb sound and legible dialogue. I simply do not miss rear channels (most have the ability to "project" the rear information - sometimes quite spooky), or the wiring. In a combined (condo!) living space I can’t recommend the complexity of an Atmos or 5.x system. With a fine soundbar - you get a 3.0 or 3.1 system for movies and TV. One button operation.
I hope this helps with another viewpoint; really envision "life" with the equipment and what you and your significant other want to live with.

I was in a similar situation a few years back. I was coming from a surround system that was great for movies, but not enjoyable for music. I went deep down the rabbit hole of trying to get my stereo setup satisfying for music. By the time I did I had blown whatever budget for any additional surround setup up, but to my happy surprise the large enveloping soundstage, sharp spatial definition and Timbral richness added up to a movie experience that was significantly more satisfying than my surround system ever was. One day, when the coffers are replenished, I may take a stab at rebuilding a surround system, but in the meantime, I want for nothing and the music is out of this world endgame fantastic! I am simply recommending that you fully satisfy your music itch first, and then see where you’ve landed... and then plan next stage. Problem with starting surround first is that it rules out so much great gear that may blow your mind musically. YMMV
I agree that if you really value stereo music, you can't use the same gear for video.

Get speakers that suit both purposes and then set up your audio system however you like.

Then add either an AV receiver, or do what I do (but it is far more expensive) and add a really good AV pre and separate power amp - in other words two completely different amplification paths, one for music and one for video. Just takes a minute to pull the speaker wires from one and plug them into the other - using good quality banana plugs speeds it up over having to undo spades or bare wires.
