you should try to get more ventilation to the avr, maybe with a fan directing air to it.
+10 is very high level and if you'd want to do that on a regular basis, you should use separate amps along with the preamp outputs on the avr if you have them.
also try to make sure that when you increase the volume, you never hear distortion; if you can hear it it means the amp is overdriven and is clipping.
if you buy pro amps, most of them have a clipping indicator (led), and power comes relatively cheap with them.
