Thanks Stephen B.

One other issue I thought of while looking at monkeyplasms post...

I've experienced discrepancies with rated max power of different receivers or power amps when testing on my AP gear. My own fault, as
I realized, when I used a lesser power cord it lead to not being able to achieve the max power output listed, or anything close.

For example, if a device stipulated a 14 gauge power cord and I used a lesser cord, such as 18 gauge, I saw a significantly less available output capability than what I expected. In this case, about 25% less max power capability.

Not just that, but when I tried to push the unit in an attempt to reach the expected goal, the results were an exponential increase in THD+N, but not much in the way of an increase of max output power.

A change to the proper power cord, resolved my experience.
