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.
seems to me

millercarbon simply will not compromise his amazing 2 channel system.

audiotroy may hope for sales, however I believe they do make effort to share their experience which I appreciate. people ask for advice, they are highly experienced and give it. take it or leave it.

I agree with audiotroy, and I said in my initial response:

Home theater: CENTER CHANNEL is a must, and at least a small pair of rear surrounds (engaged when real surround content exists) are needed.

Switch it to 2 channel if it is fake/created surround. That complicates Video IF it's sound is better without surround. Using 2 channel with video, omitting the center channel, it is important to get a center origin from the mains. 2 Channel precise imaging, in a sweet spot is of course wonderful, but add your spouse or a friend, 2 people wide, perhaps 3 (OP said 'we') and things change.Speakers specifically designed (or easily moved) for wide center imaging are thus important. 

Also consider, precise imaging for music is primarily for stationary musicians/singers, things 'stay' .... Imaging for Video is ALL OVER THE PLACE.

I have low ceilings, I've never been tempted to add height speakers or bothered seeking a good 7.1 setup to hear, I have been, and am quite happy with my small home theater.

My music system is separate, the 'real' speakers/equipment.

As I said, I used the same system for both music and video for a while, but that was before good 5.1 system/content was plentiful.
People, like my neice, many others, love minimalist Video Environments: TV/Monitor wall mounted, no deep cabinet for equipment below, no big speakers. They often compromise with wireless speakers.

Big Mistake IMO. No way to meet OP's desire for great music out of a video system.

A darn good AV Receiver is Big, Hot, Many Wires. Add Blu-Ray Player; Cable Box. That needed cabinet provides a place for a real Center Speaker directly below the screen. Real full frequency Mains. That has the potential for a darn good Music System.

Add more music sources to bare bones and it gets big and complicated, many remotes involved. Reel to Reel? Turntable? Streaming? DAC? ..... 

It can be done, but it is Hard to get right.
Oh yeah, legacy stuff,

I also have a VCR, and a quiet fanless PC (video on the motherboard), with small wireless keyboard for total access to the Internet. PC was used a lot prior to smart tv's and the restricted browsers of early smart tv's. PC has access to all content on the home network, and better processor.

IOW, a home theater has/might end up having more equipment than you start with. Minimalist system will force you to compromise in my experience.
raw 33,

You will find a lot of stuff on YouTube that you can see and hear. Keep in mind this is not an accurate sound, since it’s not a live audition but it helps. At least you will have an idea specially of what things look like and reviews as well.
If you enter the manufacturer, model numbers and add YouTube in your search, it will give you a lot of info. on anything you are looking for.
