Hopefully this is the right place to ask.
I'd like to know why some amps cost more than others.
I'd like to be able to look at an amplifier and know what components were selected and why.
I'd like to be able to build my own amplifiers.
If I know more about electrical theory I can appreciate certain amps more and make better buying decisions.
I like to learn theory, such as mechanical engineering, but I'd also like to apply that theory, and with mechanics you need a big workshop and a lot of tools, but with electrical you only need a desk.
