Luxman SQ38s or Sansui AU-111

to be used with Zu Druids MKIV.

Which amp is the best
The one you like the best is the is the best.
I can say as an owner of a Sansui amp that it will be less warm and more defined in the treble than the warmer than neutral Luxman, which I have a owned in the past. If you like the rich warm tones of a Luxman then that amp is for you. Why have you decided on these two? Have you heard them because that should take all the guessing game out of the discussion?
The one that has been Re-capped and throughly checked.
Otherwise, i would not trust an amp this old on speakers
it would bother me to junk.
