Why do preamplifiers have so many capacitors?


Saw the inside of a preamplifier, a higher model, and it had 8 to 12 capacitors. I know they are used to store Power and may regulate impedance. Are they dedicated to individual segments of the frequency curve or is it simply storing all the power to power dynamic needs of an amp whenever it's needed.  And some capacitors were bigger than others.

Or, if you want a more formal textbook, 'The Art of Electronics' by Horowitz and Hill is a bible of practical methods. A section  in Chapter 1 talks about capacitors and their different characteristics.

But also note that although materials are a good guide to how a cap will sound, the method of manufacture also makes a big difference. For example, a Relcap teflon film and metal foil cap sounds quite different from a V-cap. To me. YMMV
