I too am in the upper Midwest and just yesterday received new electronics from Hattor. They were on the truck 3 extra days due to the snow slowing delivery. They were cold when I unpacked them so I let them reach room temperature over 5-6 hours - no condensation (I checked inside) and no problems. Of course waiting longer will not hurt.
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?
