Why do you think jitter reduction is the solution, lowrider? Those DACs you auditioned have much simpler reasons for their sonic differences than jitter. I owned the Hegel HD-12 and found it to have the sound character you describe, which coincidentally has the lowest jitter specification I have seen. Can be had used for much less than your budget. Now using Exogal Comet Plus which I bought used for exactly your target price and it is pretty amazing.
The Holo DAC shadorne recommends would be a top candidate in this price category also.
Have you tried different USB cables (if you use USB)? Wireworld Platinum Starlight 7 is very fast sounding but can be mercilessly bright (not for you). Curious USB is very balanced sounding and could be what you are looking for in sound character. Purist Audio 30th Anniversary is better still but expensive.
