Ahem, I will admit it's 25 years ago, but I have a degree in applied physics and I have got to chip in here and agree wholeheartedly with this statement. Audio is a well understood physical process and the pressure waves and electrical impulses are many magnitudes greater any elemental processes going on at sub-atomic level. I had a quick look at the Bybee site and a quick read seems to indicate that he has poor understanding of how electrons migrate in a circuit and his concept of filtering them is laughable. He has school-age ideas of current "flow". Electrical signals travel at the speed of light round a circuit, but electrons don't. They bounce into each other (at a few million metres a second) and that's how the signal is transferred, not by individual electrons going round and round the wires like water particles in a pipe, but by a chain of interactions. There *is* a general "drift" of electrons in DC circuits and the Fermi Speed for free electron drift is millimetres a second. In an AC signal (like audio) they tend to just whack into each other in a very localised way and not move any significant distance at all. How do you filter electrons if they aren't all moving through the filter? A good mod is when a second designer takes the time to understand the circuits, learn the compromises taken by the original designers to reach a certain price point and carefully introduces uprated components that in effect duplicate what the original designer would have done with a bigger budget.
