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!

Yep, for sure. Since this is a $2k-ish thread (see title), can say that I currently own and regularly use 4 such products across different installations (Teac, marantz, Integra, Bluesound) and from my posts here you know my overwhelming favorite based on actual ownership and heavy use. 
Brooklyn Bridge+. DAC with streaming.  Adding an SBoster external power supply is a meaningful upgrade 
I did pick up an older Ayre QB9 DAC for peanuts as I was pretty happy with the Ayre DAC quality in my old EX8 and Ayre right now are offering an update to this to Twenty status which basically means the only old parts surviving are the outer casework!

After reading on other threads of Aurender outstanding customer service and support that has pushed the N100H way up my list of viable streamer contenders.
It is USB only and the QB9 is USB only so maybe a very good match.
Decided to go with an Aurender N100H for now.
Hopefully will be a good move.
Thanks to all for their useful and helpful suggestions
@uberwaltz,

Congratulations on your purchase of N100 and QB9. You’re in for a very nice treat. Did your N100 came with MQA upgrade?
Enjoy!
