You won't be able to hear a difference even with a main amplifier. The difference will be when you push your AVR with higher volume you won't clip it or make it in to protection mode.
When I am alone, I love to listen to loud music. Around -6 dB's to +2 dB's. My Denon X4200 would get hot whenever I played music for long periods of times. After getting my LPA-1 my AVR run nice and cool
Now, I am looking for a repair shop to fix my LPA-1. The 12v trigger doesn't work anymore, and channel 5 goes in to protection mode randomly. So, I'm currently using 3 channels only. I was told by Emotiva they can't work on this amp since it's pretty old and no parts available.
