Well, any amplifier except a PERFECTLY linear amplifier (which doesn't
exist) will produce harmonics and intermod. A class B device will
produce more than a class AB device which will produce more than a class
A device. I think most "bricks" are either class AB or B. They are
therefore NON-LINEAR devices. Any non-linear device will produce
harmonics. Now, do the amps have low pass filters on their output to
knock these down to FCC specs? Perhaps. But IMHO, even with a perfectly
clean signal on the input of an amp, the output will have some spurious
by-products. Perhaps they aren't enough to worry about. I.C.E. claims
they have never been able to measure them. I don't know. I don't have
the equipment to test it out.
