Not that hot. It only gets very warm when listening to music. I leave them on and the cool down substantially with no signal flowing through them. I think it's best to just leave them on all of the time.
Hi dallasjustice,
I am eagerly waiting for your Kaluga report.
I need a good and powerful poweramp for my Magico S5, Mola Mola may be very suitable for this task.
BTW how warm is the Kaluga when they are kept turned on continuously?
I live in Hong Kong and the summer room temperature can be quite high, particularly when there is nobody at home and the air-conditioning is shut down in daytime.
Many thanks!
CK
