Suggestions for a top flight streamer/Dac around the $2000 mark?


Time for another change and moving from my Ayre EX8 super integrated with built in streaming and dac to a BAT VK300SE integrated.
So looking to up the ante on streaming and dac sq with a dedicated streamer/dac.
I know this tech moves faster than I can keep track of!
So suggestions around the 2k mark and used is perfectly fine!
Many thanks!

I understand the D2 might not be a top flight dac but at least it gives me an option.
And I can research DAC at a later stage.
The mhdt orchid does seem to be well received.
I've owned both the Lumin D1 with the Sbooster LPS and the Teac NT-505 and while they both use the same software the Teac has the better DAC and the better sound to my ears. 
Unfortunately the Teac doesn't have a digital out.
That may or may not be a negative.  If you have a top of the line DAC already and want to use it, then obviously it's a negative.

I considered buying a streamer only (Lumin U1 Mini) but my thought process was that having it all in one box eliminates a power cord, a set of interconnects, and that DAC technology is somewhat mature now, while streaming technology seems to still be evolving.  

The TEAC sounds better than my BlueSound Node 2 did using my Auralic Vega (which was a $3500 DAC when new) as the DAC.  I don't miss the transition from the DAC in the TEAC from the Vega.  I'll never know now, but I doubt the U1 Mini / Vega combination would have been better than the TEAC and it would have been more expensive.

I feel like I got more bang for my buck with the TEAC and am very pleased with the sound quality.
