Recommend A New DAC Between $1000 and $2000

Border Patrol might do it for you also maybe an AN Kits Dac.

The black ice I owned the tube gives it a warm signature but very rolled off 

the Denafrips basic Aries is much better ,the pontus2+ a excellent dac 

and the new Gustard r2r26 is excellent ,add the synergistic purple fuses it is better then my pontus2 dac   
I am saving for a true reference the T&A  200 dac ,which is exceptional .

I’m using an smsl su-9pro it’s natural sounding since you can turn off all filtering and can reach 135db which is also very nice and the price is 500 usd. 

+++ Denafrips Pontus II. I have had mine for nearly a year, and still love it. Certainly the best DAC under $2,500 IMO…..and I’ve heard a few. It has the traits you are looking for, with just a hint of warmth.

The newest Pontus II 12th Anniversary edition has even more improvements over the standard DAC…..and for $1,850

Bryston BDA-3 fits your requirements. Used should be around or slightly more than $2000’.
Chord Qutest is fantastic as well especially with the warm filter engaged.
