Need Opinions for Streamer/DAC [One Box - Not Separates] Budget Approx. $ 5,000

To circumvent the wireless requirement, just get a range extender, and plug in near your audio system. Typically these work better than internal wifi. I have had several... including over $5K that simply did poorly on their own wifi. I know of a number of $100K systems that work this way, including my own where streaming sounds as good as vinyl. 

This will open up a wider world of streamers. Have a look at Aurender.

Thank you all for these suggestions. I will certainly research.

BTW I have a UniFi network set up in my house and am using the U6 PRO as an access point and have AT&T 1 gig fiber in passthrough mode.

I was in the same boat and thought I needed something with wifi. Turns out the range extender idea is very reliable, meaning I was able to look at all options instead of only wifi capable units.

In my case I use an Asus brand router for my main network, so I picked up another Asus router and set it up for their proprietary Ai Mesh mode. It works flawlessly. Later I added a 3rd one to improve coverage on the far side of the house. Now if I walk over there with my phone, the system will hand off coverage to the closest router. Pretty slick.

Once you have ethernet as an option, there are a lot more interesting choices available for streamers. Especially if you want a one box solution which inherently cuts down your choices compared to separates.

The TEAC UD-701N is the top dog for me in the $5K range! Under the hood, it’s the same unit as the $10K Esoteric N-05XD.
