Combined Streamer/DAC/Preamp

I'm trying to put together a system for my bedroom (not my primary system) and I don't want a complicated system with lots of boxes. I have a DIY Purifi-based amp with balanced inputs that I built in a small chassis that I can mount vertically on the floor against the wall, so it hardly takes any space.

I'm looking for a single box unit that can encompass the rest of a digital streaming system. I have a Roon server and also subscribe to Qobuz, Tidal and Spotify (the latter mostly for podcasts and listening in the car), so I'd like a flexible streamer that can act as a Roon endpoint as well as run Spotify Connect. And I'm looking for balanced outputs.

I'm currently using a Bluesound Node 2i feeding a Schiit Yggdrasil which is my backup DAC. This is one too many boxes, and this forces me to use the digital volume control on the Node 2i. Since I usually listen at low levels in the bedroom, this is a significant compromise in sound quality. 

I'd like a box that is no bigger than the Yggdrasil, with a true built-in preamp with analog volume control and balanced outputs. 

The Auralic Vega G2 looks just about perfect, but it is somewhat pricier than I'd like. Any comparable, somewhat lower priced, alternatives? I'm happy to buy lightly used (no more than a few years old) but would (ideally) like to keep it under $3K. I might be able to find a G1 at that price, but I'm not sure how much SQ I'd be giving up. 

Thanks.
