Yes, I am VERY interested in knowing how close the clip indicator lights are to actual o-scoped clipping.

Yeah it was at 14.2 volts. As for the clipping on the scope, by the time the lights come on it is clipping a little, but that's okay. If you want a "clean sounding" audio system, it doesn't mean setting the gain so the amplifier never clips. If you did, the absolute highest musical peak would occur at the threshold of clipping and there would be no audible distortion. In order to find a compromise between high signal-to-noise at low listening levels and low distortion at high listening levels, you need to understand "Gain Overlap", which is the amount of input signal that overdrives the amplifier's input. I use a 1kHz -5dB test tone, but many people prefer -10 dB of gain overlap. I prefer a cleaner sound at the expense of sound pressure levels.
