Eric, perhaps my jaded view has something to do with my experience with 80's gear. My Luxman R-115 developed a volume and intermittent channel problem that got worse with time. A yamaha cd player starting skipping after a few years. My buddy's proton amp went south after 20 years. Though I guess neither one of those would be considered high end.
The thing is, the beginning of the 80's was when all the big brands reduced the quality of their lines from what was offered during the golden age of audio, the 70's. I suspect the truly high end managed to avoid this. The Conrad Johnsons and Mark Levinsons of the era probably did just fine. Carver made quite a name for themselves, but their gear didn't last forever.
