krell amp and preamp keep for life.....

hi, to all krell fans (i'm one of them) i just bought a set of vintage krell amp and preamp (ksa 50 and pam-1) that are really good sounding. I can't believe when these two items are combine together and they can create magics. Even as of today (30 years later) they are still a champ. So now i would like to know does anybody has a set of krell amp and preamp that they would like to keep for life. ( i have one now, the best part is they are still serviceable )..go krell for life
