Personal amp evolution


Seeing the over night success of the speaker evolution thread, it may be interesting to see what type of amp(s) we have all run. Same deal as the other thread-we will sort of create a puzzle of our systems you'll have to visit multiple threads to put everything together!!! ;)
For me I started:
Adcom GFA-565 monoblocks
Rotel RB-990bx
Jeff Rowland Design Group Model 5
Balanced Audio Technology(BAT) VK-60

either a CAT JL2, BAT VK-75se or Tenor 75Wp on the horizon.

Lafayette LR-500B receiver (1969)
Dynaco SCA-80 intergrated amp (1971)
Sony TA-1130 (???) intergrated amp (1974)
GAS Son of Ampzilla (1978)
Hafler DH-200 (1980) (used both Hafler & GAS)
Berning EA-230 (1987)
BEL 1001 (1990)
Music Reference RM-9 (1992)
Sony year of 1978( ia do not remember) it had greens leds,marantz sr5300, yamaha rxv-795 a, rotel rb 1070,macormack dna 1 dlx, AR vt100 mkII, and now the best I heard Gamut d200 mk3.
1967: SAE MK IV x 2; SAE MK III; SAE MK I pre (early SS heavyweights used with my Infinity Servo Statik I; eventually gave III and one IV to my kids, still working. One IV eventually lost a channel; it and the I in my attic now; well-made stuff)
1998: Creek 4240SE (gave its all trying to drive my Maggies, then croaked; dumb move on my part, but sounded pretty good for a while on classical music; in my attic now).
Current System
2002: Denon AVR-3803 (pre/pro and 3 amps for surround channels; pretty nice DACs for midfi receiver, but just not enough juice to make my full-range Maggies sing)
2004: Adcom 5802 (drives my FL/FR channels; Nirvana with my Maggies)
Next update in about 20 years I hope, although the heat of the 5802 may impact its longevity. Fortunately it resides in a room adjacent to my listening room so I could use an AC fan on it. Anyone had one for say five or more years? care to comment on overall ownership experience?
