If you are talking the speed of electron/signal,it's not an issue at all.
Transient respond/speed is a completely different story.

Amplifier Speed
For analog power amps should any consideration be given to the amount of time it takes for the music signal to travel through a amp's circuitry? For instance, if I'm bi-amping with two very different design amps can one amp "process" the music faster than the other, or is it just not an issue?
