How about the Marantz Ruby amp? I nabbed one for less than $3k, open box
it certainly does not sound "cold" nor "clinical" , nor does it sound overly warmed nor colored... just clear, spacious, image-rich, robust with great dynamics, headroom, reserve
however, it is an all analogue design... my dac work is done well by the accompanying Ruby sacd player
and @nonoise +1 ... like nonoise, I'd suggest: If you want to go "higher" (though honestly there isn’t really all that much more "up there" from the Ruby), there’s the newish Technics, like the su-r1000, which is not exactly D but in the ballpark and has excellent dacs built in and includes what is supposedly an unsurpassed phono section (if you’re into vinyl) . The less expensive Technics g700m2 is also an option, if you want to go smaller and save some $$.
