Adcom pre amp versus Van Alstine

+1 @dweller I had an Adcom GTP-400 and it was "meh." AVA would be better.

This modwright is pretty nice, too:

The Emotiva DAC/PRE (Xda 3) is a worthwhile option <$699, true balanced. Very nice YouTube review

Can't remember what the model was, but may years ago I owned the top of the line Adcom Pre and really liked it.  They are so old now I would be very worried that the caps are drying out and the SQ will degrade.  

apples (Gala) and apples (Heirloom)? 

rick_n: I agree with your post regarding old audio gear.  All electronics have a life span.  Does one really save $ buying old/used components when you consider how much life is left on that product?  Been there done that many times. I now prefer to stick with new.
