Lifespan of a quality solid state amplifier?

2 old "low end hifi" SS amps chugging along: 1. a Hitachi receiver SR 2000, circa 1981, 70 W per channel continuous, inherited from my now deceased mother-in-law, has operated without a problem. I use it in my home office. It is on now playing blues..:) 2. my Hafler 9180 purchased in 1995 for $477 has never malfunctioned or shown any sign of sonic degradation.....:)

Ah, luring the arrogant, denigrative tendencies out of those who simply can't resist the temptation/obligation to grace these pages with thier personality dysfunctions, the holier than thou, "higher end than thou" is a pleasure. Gotcha!:) They can't resist an opportunity to prop up thier pithy, fragile self esteem with yet another childlike attack, "mine's better than yours!" Your mission is not accomplished but mine is! Baiting curmudgeons is easy. Reveal yourself for all to see. They think they gain power thru these inconsequential immature rants. The inner weakness drives this behavior. They remain: WEAK...awww

Thanks Cathode for being a member of the "non-negative" group. Unfortunately, there are always members who are obligated, predisposed by personality to inject their conflict driven thoughts in conversations where conflict wasn't sought. They enjoy this denigating activity too much to refrain and seek out places like Audiogon where their alleged "knowledge" gives them some kind of entree. Some also actually bring some "useful" information to the discussion. Too bad the "salvageable element" of their post is tainted by the putrid grime of detritus ridden tendencies. Others just blurt out their childlike venom like they use to do at recess. Either way, the members not predisposed to or baited by this type of obvious and weak behavior, continue on here engaging in discussions with reasonable and like minded people. School's never out for some.
