I think many Burr Brown based designs will deliver the warmth that you’re looking for. Bluesound Node uses Burr Brown (except for the latest X which uses Sabre).
check out the Parasound Classic 200 (preamp or integrated) which implements the PCM1798 quite well and can be found used for about $1000.
Or, if you use Roon then the best that I’ve heard in that price range is one of the old Parasound D/AC 1000/1500/2000 which used the PCM63. I mention Roon because that chip can only accept 16/48 so you’d need to set the Node output in Roon not to send a signal higher than that sample rate. As an aside, Mike Moffat is on record saying that the PCM63 is the best DAC chip ever made. The fellas from Pass Labs are also on record saying the same.
