He probably meant that transistors turn on and off rather than resistors (if you think of electricity flowing through a wire like water or gas through a hose, then you can think of resistors as being like those little hose clamps they use in chemistry labs to control the flow of a gas or liquid... most are fixed but some, like the volume control, are variable... rough analogy). Technically wrong anyway since transistors can switch orders of magnitude faster than tubes, and in class A ss amps, the transistors are on all the time like a tube anyway, and in class AB amps they don't switch on and off either... transistor is already on to the linear part of it's conduction curve before it drives the speaker (there are pulse amplifiers and integrating amplifiers that do switch but not typically used for audio). Don't know what is meant by amp speed in an audio sense... perhaps tube amps having more even harmonics while SS amps tend to also have stronger 3rd, 5th and other odd-order harmonics. Or maybe an amp not acting like a variable delay line that does not distort the sound envelope (high frequency components of a violin note reaching the output at the same time as the low frequency components instead of one part being speeded up or delayed and altering the envelope of a note, but I'd call that smear not speed). Someone want to expain just what "speed" means in an audio sense... is it just slew rate or something else?
