I've had (and still have) three speaker systems "for life". KLH Model 5's, bought in 1972; B & W 801 F's bought in 1982 and ADS 1290's (with ADS 300 back channels) in 1992. I "just" bought a pair of Martin Logan CLS's (in 2007) and have worked them into the mix. They've all been restored at one time or another and are still going strong.
