Need a DAC Recommendation.

Just another shout for Denafrips, all the Denafrips DACs are excellent, the Terminator Plus tops the range and that’s a dream piece of kit. 

Chord qutest or mojo... Chord do their own DAC chip it is the closest I can get my streaming to my $4k vinyl rig plus it allows USB, bnc coax and optical inputs... It also has further filters to subtly adjust the sound if your set up to analytical for your taste. 

I second the Qutest. It really sounds wonderful in my system. 

Teac NT-505 or Topping D90 or SMSL400

Surprised no one mentions a Border Patrol. The lowest tier model is @ $1075. It's an R2R dac based on a Philips chip with either USB or coax @ the price. I own one and it sounds great.
