Replace or Repair Adcom GFA-565's

The other day I put up a post about the "Adcom GFA-565's with cancer of the Driver PCB". I have been kicking thoughts around for the last few days, pondering, what do I do, repair these these Adcom GFA-565's, or replace with either of these: Adcom GFA-5802 or Rotel RB-1080. Sonically which is better from other user's experiences??? I can get these monoblocks repaired for about the same as the price of a used GFA 5802 or the Rotel RB-1080. The selection of whichever I decide to do will be running a pair of Infinity Kappa 8.1's which can handle 300w rms. I am really having a difficult time making a decision here. ANYONE have any suggestions? Any help is appreciated.
