Curious where this mass dump is happening.
If I owned any AR gear I would certainly not be getting rid of it. It’s tube gear, which is ridiculously simple to repair.
Consider other gear that became unavailable, which went up in value once it was no longer available. The Oppo player is a recent example.
Look at gear from the past. The Marantz 7 and 10b tuner come to mind.
History is filled with examples of gear that has gone up in value.
Getting rid of the components would be silly if they were making you happy with their sonic presentation.
Please, link to some of this supposed dumping?
