I'll have to print out and compare specs again a little closer. Hard to believe adding the amps is only an extra $100!
Heat, almost certainly higher for the AVR (any AVR), but not a problem for me at the moment. I have enough space around the AVR and cut open the back of my console for more airflow (and easier access to all those &^#@ wires!)
Balanced would be as plus as my main amps f(Emotiva) or L/R/C and surrounds have balanced inputs. However, I am currently using the amps in my Pioneer receiver to drive the rears so having the amps would save me having to buy one more amp... I am not sure there's much difference in balanced runs for 6' in a consumer system (100' snake at a concert, yeah; 6' at home, not so sure) but have no way of telling if the amp's sound would improve.
