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?

Obviously turn it off overnught if not playing..
Class A runs hotter on idle. Just warm it up BEFORE play, off after. 
Prepare to pay the power company.

You have to measure the temp of both heat sinks under the hood with an infrared thermometer. If one is much hotter than the other, then it's a problem. Heat sinks shouldn't vary by more than 5 to 10 Celsius. If both sinks are the same temperature and the amp isn't tripping off on thermal overload protection, then it's okay. Unless you fiddled with the bias adjustment pot, which I assume you didn't.

call parasound and ask them if this is normal and if they recommend you shut down or place into standby when not using

looking at hint6 specs it has a ’high bias’ class a/b amp section, so yes it is quite possible it would run fairly warm in normal operation, and it is likely why they give you a front panel standby option

70 watts is 70 watts. 
Specs says it idles at 70 watts. That is going to be warm to the touch for me an old mechanic and HOT to someone that has girly man hands. :-)
