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?

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. :-)

My FW J2 runs hot. That is even taking the nerve damage to my hands into consideration. It sounds great,and makes a nice space heater in the winter months. I wouldn’t have it any other way. I also don’t leave it on 24/7.  It takes about an hour or so to hit full stride. 
Call Parasound and ask them.  They might say it's normal or they might want to have a look at it.  It might be running hot because of a problem like hf oscillation or a ps problem.
