..... In the sense that I've bought a lot of expensive gear over the years, much from manufacturers that are either long out of business or under different ownership, that I'd like to keep running. Read an interesting article in Stereophile today (yes, I still read magazines ..... drive a Model T and have a landline phone) about longevity versus performance. I'm in my mid 50's, hearing is not getting any better and thus I have no need of 'better' equipment. But I would like my gear to at least last as long as I do. I've found a really competent amp tech (former Krell tech), and he's already repaired a critical amp that I feared was to become an expensive paperweight (it's the 'brains' of my Genesis speaker system, so not easily substituted). I have also bought up parts and components where I could, though key 'holes' exist.
