How hot is too hot?

When i leave my Parasound Hint 6 on overnight, it is hot to the touch (top grill), not warm, in the morning. There is nothing on the sides and 6 inch clearance on the top.I even tried switching the input to something nothing is connected to - like AUX or PHONO. Doesn't help. I have to turn it off now when i don't use it. No big deal, but it seems like something must be wrong to produce that much heat when not in use.

Is this normal? What part of the unit produces that much heat? What can i do?

Several decades audio repair, and can tell almost instantly whether unit on 24/7 or shut off when not in use.
The heat cooks the components (which are designed for heat to a point) AND the solder, which in units made after 2006 will be Lead-free solder and does poorly in high heat cycle environments.
My experience the solder joints will fail before most components.

Turn it off when not listening, solid state warms up very quickly. I get home and fire up the stereo and it's ready for listening within 15 minutes.
My 3 cents (inflation)
