I think this conversation would be interesting related to speakers.
Clearly higher speakers are incredibly overpriced as demonstrated by a used market which prices them at 50% of list after two or three years. And this is from a dealer who no doubt is paying 25% less than what they are trying to sell it for.
Speakers too terrible in the used market. An amplifier is a bit more rugged and handles time a lot better. Not sure how pricing of older tube versus solid-state amplifiers compares
