Streaming Dac $5000-8000

Hi there. 
I am after a streamer dac one piece unit  

ideally with a very natural sound, slightly warm midrange, and with good streamer app…

its for use on harbeth shl5 plus  

was thinking lumin t3.  any others to consider Like auralic Altair g2.1? Auralic Vega is a bit over budget  

moon seems to be well regarded, but they have a big gap between the 280d and 680d.   390 would be overkill as don’t need the preamp 

I like the luxman d03x cd player sound, but that doesn’t have a streamer  

thanks
