" That way you could clip away all night without overdriving the woofers. The exact opposite of an "over-easy" limiter."

The NAD soft-clip was a hard clipper on the input to the amplifier. Never lost a driver in a club where there was NAD. On an oscilloscope there seemed to be no difference in the amount of clipping, but the amplifier stayed under loop control and the woofers did not fail.

" You might need a circuit to keep the signal centered around zero. "

I've given some thought into a circuit like in the Crown MA5000VZ that could be fitted into an existing design, or an NAD type circuit.

Wowee. A 12yr long thread. I am also starting on a P500. For now it has a blown 15 amp fuse. And the left side signal led is lit all the time, right side fuse holder is broken.
I've ordered those, will fix and move on up the chain to troubleshooting it.
Thanks.
Srinath.
