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?
