Coupling Cap Types and Voodoo Parts?

[makinrose]

It's been a while since this thread was started. I did quite a bit of experimenting with ceramic caps v.s plastic caps since then. In the end I came the conclusion that I prefer to use polyester or polypropylene. Better clarity is what I like. To my ear the brand and construction of plastic caps doesn't make much difference as long as it's the same dielectric. I know there are people who claim foil/film is better than a metalized cap but I cannot hear the difference. Overall, the experience has reenforced the notion that you need to be using quality parts, but the circuit design is where most of the tweaking really needs to occur. Over time I've become far less precious about copying old amp circuits and more concerned about building amps that are a like the versions of those amps that players have in their heads. Just my two cents.
