Jorge- You flatter me, but to be mentioned in the same sentence w Steve Mc is an honor I do not deserve. I am a consumer of high end audio; Steve is a creator! There is no comparison. But many thanks for the kind words. As far as the OP's question, yes of course everything deteriorates w age ('cept for vintage winos like me and Steve) but unless your particular amp was v early in that model run, or was pushed hard w/o adequate ventilation (heat is a major killer of electronics) its likely to be good for quite some time.
Cheers
