Years ago, I had an amp with meters. I seem to recall that when the needles hit 0db, the channels were operating at the rated max power.

Although I've never heard any distortion, I really have no idea how much of the 7500's headroom I'm using.

Is there any significance to the 0db volume setting on the 990 in relation to what is being output from the 7500?

Does anyone know of a way to "meter" the power output of a 7500 while listening to music?
