TOTL cool running amps with fast 'warm up' time?

Thanks for those suggestions. This is for a theoretical end game system down the road. For now very happy with pass labs. If pass didn't generate so much heat though i'd prob stop right here. I may still end up staying here and accepting the heat because the sound is amazing.
Don't know much about AVM, will look into it.

Ya  rowland and boulder seem interesting. 

@mijostyn did you hear either? 

@soix will look into clayton
