A used Meitner MA3 will fit your price range and primary requirements. It has integrated Roon streaming.
I've owned the Sim 380DSD which I really liked, the Bricasti M3 MDX which I liked but found it leaner/more-analytical than the older and less detailed SimAudio (but maybe more musical to my ears...). I now have the MA3 and love its sound signature; it has lots of detail (but not super-detailed or analytical), never fatiguing, smooth with an almost liquid characteristic to vocals, strings, etc.
