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.....:)

How would you know if your self described "low end" systems have deteriorated when they don't sound that good in the first place.

You have just put your finger on one of the best things about going sub lo-fi. They never break and if they did, you wouldn't be able to tell the difference. Lo-Fi Rules!!

But- you won't want to listen to lofi all that much either...

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
