One aspect I didn't read in this thread is 15/20 year old "sound" / technology vs. new. Aside from the A, AB, D and other variations, is it worth spending $5K / $10K on a manufacturer refurbished 15/20 year old statement/hi end amp or are you better off spending that money on new or only 5 year old technology. If the old stuff is manufacturer refurbished, then it'll likely last another 10/20 years. Does anyone own an amp or other gear, 15/20 years old, that if thoroughly gone over could compete in today's new or slightly used market at the level it was at when bought new?
How old is too old (for SS gear)?
I've personally not been too concerned about the age of used solid state amps and preamps, but recently a few pieces of gear I've purchased have either A) bit the dust or B) starting to make weird noises.
So now, I'm a bit gun-shy about buying used gear much older than a few years.
Do you have a certain age limit when considering the purchase of used gear?
Thanks.
