Thank you agree completely that AVR ratings are misleading. Don't think any do full power rating with more than 2 channels. Even my own pro AVR has many different Ohm ratings from 8 to 4 all 2 channel and 1.0% THD. { Teac Pro Tascam 7.2}

The addition of my power amp has added a lot of bass to my towers that wasn't there. To me it's fuller even at low volume.
My small PB1000s light doesn't even activate till over 50Dbs.
