Here's a question for all you EE types out there.

In looking at technical information on amplifiers, some are said to have a "complimentary" or "quasi-complimentary" design. Anyone care to offer an explanation on what a complimentary, quasi, and non-complimentary amplifier design actually means?

I've searched around a bit, and I can't find the answer. I'm not too hung up on it, I just like to know what I'm reading.

Thanks!

The terms refer to the layout of components in the output stage (the part that powers the speakers) of an amplifier.

This is the best info I could find on the subject:
