The obvious seems to have passed you by. Ask your dealer. Get anything they say in writing, then you can follow this advice and use it as evidence if you need support / make a warranty claim.
starting equiment that ic cold from being shipped
Is it a real thing that you court problems if you turn on an ice cold amplifier or pre-amp without waiting 24 hours for temperature to rise. I have long awaited Krell FPB and KCT shipping tomorrow, It's single digits in the Midwet. Should I wait a full 24 hours for the equipment to warm inside before introducing any electricity into the components?
