thanks, doc. that's a nice story, and to hear first hand experiences. i never thought about technical computations for the avr vis-a-vis an amp, i always just assumed it's ok when the avr does not clip or conk out.
some veteran audiophiles even recommend that your avr should be at least two times powerful than what your equipment requires. I myself believe in that recommendation. They say its overkill but you can hear the mark improvement that it makes.
