confused and don't know what to do

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.

raw33,

A while back I started a thread here referencing this same topic.
I have not looked at it in a while, since I came to my own conclusion after a lot of research and auditions. If I remember correctly it’s called amplifiers good for music listening or 2 channel listening.

Anyway, my conclusion was to separate the two. If you don’t, you will never have the best of both worlds. First and foremost, what is your budget and what is your priority. If want to keep them together then buy based on your listening priority.  Keep in mind home theatre requires accuracy and forwardness which might night be ideal for music listening. Also, you do not have to spend a lot for your home theatre for it to be good. In my opinion you should pick out a pair of speakers that call out to you sonically and then pick the rest, since you can always tame your speakers by 
positioning, working with electronics, wiring, etc. Once you pick your speakers do your home work plus audition your ears out..lol.
If you want something you like and not be disappointed when you take it home, take your time. Remember some dealers will let you take gear home to audition.   Anyway, good luck and have fun....

+1 to audiotroy and mtrot approach. I used to use a receiver as preamp but upgraded to dac/preamp. Remember that any DAC used in this way will have to have analog inputs. It does complicate the system use and remote control, esp with a music server, but I LOVE my combined 2ch/HT system now! We really need some idea of budget to give better recommendations on gear. I use Anthem MRX-1120 for all other channels, and Bel canto DAC3.5mk2 with Mark Levinson ML-532h amp for 2ch. The system kicks. The new Bel Canto Black EX DAC-pre looks really nice if you can afford it.

If your room is large, I highly recommend multiple subs (a swarm), even if you won't play them loud. I suffered for 20 years with what I would call a hollow bass sound, and adding a 3rd sub on the far side of the room solved that. It's like magic, and believe me, I tried just about everything else.

I also finally got acoustic treatments, and they were the icing on the cake. In your room, these will be absolutely essential. Keep in mind that if you go with receiver for surround only, it will not be able to correct for your 2ch, and this is actually a good thing. Also, no amount of room correction can compensate for a room with many reflective surfaces. I recommend GIK acoustics as very helpful in overall design with many options and good price/$.

I wouldn't skimp too much on cables, but I would save really expensive ones until the end. I'm a firm believer in ALL cables affecting the sound. Best of luck, and come back with more information as your system progresses.
