Streamer Recommendation.

You’ve got a really nice system there. I particularly love both Joseph Audio and Luxman. I’m an Aurender dealer, so take that into consideration, but there is a lot of love for the Aurender N200 on this forum. It retails $6,000, and while it doesn’t have wifi built in, I would encourage you to get a Netgear Orbi mesh router and satellite system for the home, which can be had for less than $1000. This would allow you to both have faster, more reliable internet around the house and be able to hardwire with a quality ethernet cable in from a satellite into the Aurender. This solution will deliver much better sonics than any unit that has wifi built in as that will be a major source or noise and interference. Aurender does also support wifi adapters with Realtek chips, but I would suggest going the mesh router / satellite route for improved sonics:

I'd be happy to answer any other questions you may have more directly over the phone or via PM.

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. 

i think auralic is the one major streamer maker that prefers wifi over hardwire connection for network signal
