Why do preamplifiers have so many capacitors?

That's some serious stuff to be replacing 50 capacitors. What type of beastie Dac are you dealing with? Would love to learn more about all that you have done here. Clearly you must know a little bit about what goes on inside a box.

I commend you sir

I dare say many who buy preamplifiers have no idea how they work internally. It would be wonderful if there was a diagram, a visual guide, allowing someone to understand the internal flow of a preamplifier. Further I never see commentary explaining the flow, and variations, within a preamplifier.

I think many would be grateful with something that illustrates how these mystery boxes work.

Which preamps have the best use of capacitors and tubes? Since that seems to be really important for preamp.

am told Teflon capacitors are really good and use of foil, whatever that means
