Just a guess here, but if you would go the route with a vacuum sealed bag that you eliminate condensation and would benefit from free cryo.
Storing Unused Audio Equipment
Can unused amps, preamps, DACs and CD drives be stored in an outside non-temperature controlled storage locker? Is there anything about the electronics of the amps, preamps, DACs and CD drives that the freezing cold can ruin? It gets below zero degrees here in Vermont and according to google the average temperature in the winter is 22 degrees. I am two hours from Canada.
Thanks
