Streamer Recommendation.

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. 

Having been in a similar situation and in the position to borrow several DACless  streamers from friends and stores including Moon, Naim, Aurelic, Rendu, Lumin, Stack and Lindemann. I found little to choose between them re sound quality.  Of them all I preferred the Stack, with the best balance in my system of detail, soundstage and presence. It was however a disaster to setup and or update, if a Mac user just don't bother. Eventually I bought the Lindemann Limetree Bridge, which via my Denafrips Ares II sounds beautiful. 

Definitely auralic.

There is a new set of Innuos streamers about to be launched. With your budget I’d look at the Pulsar which includes a USB reclocker and decrapifier. InnuOS Sense App is superb.

I can strongly recommend an Auralic product. I just took possession of an Altair G1 and am very impressed with its overall performance. I think the Vega G2.1 would be a great fit for your system.
