The mass of the elastomer is very low. It will revert to room temp very quickly. Alex just put ear muffs on it:)
Made me go and check. OP bought a nude. How inconsiderate. Oh well, it'll warm up all the faster.
My Koetsu has a nice big brick of a body around it. Think I'll give it a minute or so to get nice and warm. Then another few minutes for the heat to sink in through all that quality Japanese aluminum and whatnot. Then have a listen. So in other words same warmup as usual for everything else, only tonight for the first time physically heating the cartridge up. Gosh for the first time kinda wishing I had one of those trick temp readers. Oh well. New trademark: Go and touch. You will feel.
