Streaming Dac $5000-8000

the bricasti's are terrific, very musical, and according to esteemed member @tvad the m3 plays a touch warmer than the m1 mdx se (which i had)

Another vote for Bricasti but you will likely be dealing with complexities of ROON. If you like Luxman sound, I suggest the combination of Luxman DA-06 with Aurender N150 or N200 and you get the preferred sound and a robust straightforward app interface with a very high quality streamer. 

there's TWO great option, 

1. iFi Pro iDSD,

all in 1 dac amp pre streamer with tube mode. 

2. Shanling EM7, 

all in one solution with unique Android system Streamer. 

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.
