Seeking advice for speakers for my Family Room

IMHO the biggest issue with your setup are the room acoustics.  There are a lot of hard surfaces and it is a rather large open space.

May I suggest instead of adding blinds to the two windows on either side of the TV, use floor to ceiling drapes with back out linings; close them when doing critical listening sessions.  Move your speakers out a bit wider so they're in front of the windows.  This will give you some absorption/ diffusion on the front wall and a wider soundstage for movies. The big factor is the floor.  You need a much larger rug, preferably with a thick rug pad.  Most interior designers specify a rug large enough so the front feet of sofas and chairs in the seating group to on the rug.  Bigger is better.  Perhaps move your existing rug to the other seating area group.  Next, check out GIK Acoustics or Acoustimac for acoustic panels with printed art work to replace the smallish artwork over the side sofa; this will help with first reflections.  Your wife might like the fact that she can choose new drapes, rug and artwork.

Here's a slightly more extensive issue; remove the marble slab behind the TV and possible replace with a diffusion panel from GIK Acoustics. They make some contemporary style panels that would integrate well with your decor. Luckily your main seating sofa is open to the Kitchen behind, which is to your advantage as far as room reflections.

Lastly, (sorry for the long winded response) look for speakers with soft dome tweeters, stay away from horn speakers in your environment.

KG,

Glad you're addressing room acoustics before making any equipment changes.  You can spend a fortune on equipment, but if your acoustics are bad you'll never get great sound.  I don't think you have to go overboard on treatment either.  Adding a larger rug and heavy drapes will go a long way on lowering the room glare.  A  2" canvas covered art panel will do some good and won't stick out visually in a Family room setting.  If this were a dedicated listening room I would go with 4" or 6" thick panel; I'm considering the spousal acceptance factor here. 

You could use a much larger artwork here or perhaps a two piece diptych. These really are a relatively low cost way to go.  Do all these changes one at a time and you'll see how each one helps.  Let me know how it goes.  This is one of the fun parts of this hobby, these small changes can add up to big improvements.  Hey, where is your sub located?

kgtunse,

You might take a look at the NAD T788. Kind of pricey, but when you add the MDC2 BluOS-D module to it (for $549 more) you get Dirac Live Room Correction  and a nice music streamer together.  Check out the NAD T788 review on AV Forums from Oct. 2020 for more info.  I would say whatever you do, don't make any equipment changes until you have done the room acoustic changes. I think you'll be surprised  at the sound improvement. This will also allow you to make a more informed choice if you have a chance to audition any gear in your space. You are correct that the open Kitchen space behind you is working somewhat to your advantage. 

I don't know if you do any streaming, but I just replaced a Sonos with a Bluesound Node in my system last night.  Sounds much better, soundstage and imaging are improved.  I'm waiting for my Denafrips Pontus II to arrive so I can bypass the DAC in the Node.  

I forgot to add;  Check out Anthem MRX receivers or separates. I think they sound great and they have a plethora of control features.  Their room correction program is very good.  I've heard them in multiple systems and they always sound good, especially in difficult rooms.
