Accuphase A-35 or Accuphase P-4200

I'm interested in buying one of the following:- Accuphase A-35 or Accuphase P-4200. Does anyone out there own or have heard either of these components. I've heard good things and of course one is Class A and one Class A/B so there will be merits with one over the other. I listen to mostly classical music and own the Accuphase C2420 Pre and DP-510 CD Player. I can't run to the more money components higher up the ladder but evidently these are special for what they are unless anyone has any negatives.

Dip in (and then out) HERE
