Is this too hot for my preamp? What should I do?


Hey guys,
I have a pair of Jeff Rowland monoblocks, and these puppies run warm. The amps are stacked one on top of the other, and on top of that is my Mark Levinson pre.
The pre is rather warm to the touch, the amps are radiating heat.
Should I change this? Or I am being dumb, and the pre wants the heat, as a warm unit sounds better?
Thanks

If you’re looking to upgrade in a couple years leave as is as you’ll probably have no choice. Yes... give them some room to vent. 
Heat kills....if you can get a rack with a shelf for each component it goes a long way toward a long life.
