Streamer Recommendation.

If you like music discovery you should really give ROON ecosystem a look, especially with a $7K budget. If you just like firing up an album and listening (Ron Popeil ,set it and forget it) then go with a one box solution.

Yeah do the the mesh network thing and have a node right at your rig to plug into.  I would also consider  Bryston BDP and the fairly new Moon Neo Mind 2. 

With that kind of budget you could also explore a ROON configuration. 

OP has made no mention of wanting to rip and store but getting all kind of recommendations for it.  🙄.

+1 on the SGC and Rendu if Roon is something of interest. 

i would add though, in my music room i am using a mesh router satellite to deliver a ’virtual’ ethernet feed into my roon core/streamer, and it works very well -- one day i may bite the bullet, drill through and run an actual hardwire ethernet, but so far i have avoided that need with excellent performance with the mesh system

This. I don’t even have a dedicated backhaul on my mesh (dual band) and it works fine. Thing opens up flexibility as well. Luckily my office is in the same room as the base node so I got 2 PCs, Network storage unit and an old Sonos zp90 hard wired to the base and my main rig has a Roon core host hard wired direct to a sat node . Every now and then I gotta reboot the base but its rare.

I wouldn't even want a streamer with wifi hardware inside of it.
