Looking for a DAC under 2k

I'm using a Small Green Computer Optical Rendu to bring usb to a DAC.
Looking for a new DAC around 2k new or used.

Recently, I had a Border Patrol Se-i which sounded beautiful with a great soundstage and a relaxed sound. Unfortunately, dynamics and bass definition were weak.

Next up, I tried the ifi Pro iDSD. Detailed and clean, but lots and lots of settings to play with. Became noisy after a couple hours and eventually stopped putting out sound and went silent. Can't deal with that kind of poor quality, but really would have prefer a little warmer sound.

I borrowed my Chord Qutest from my headphone system. Very good with my tube headphone system, and not bad on the speaker system, but would like something a bit more analog sounding, like a Border Patrol with dynamic punch and clearly defined, not muddy bass.

TIA, for suggestions.
