@jc51373, yes, transparency has its +s and -s and the tube warmth is definitely missing. In the end I went for the detail but I appreciate the difference.
@yyzsantabarbara Boss I am an impecunious professor. I did try the LA4 at some point, not for me. Though at some point I will try your other suggestions. I have the 891 with the 761 on another system at home, so more of the same, but better (?). I will check out the imersiv D-1 DAC if I can. (BTW, given my bias for transparency and detail over warmth, fiber made a significant difference to my --- limited --- audio life. Thanks!)
