If you can't tell me the Q and self resonance of those fancy foil inductors then you are buying them for looks. Educate me on why a foil inductor is better. There was no need to illustrate my point, but thank you for doing it. There are a lot of things that matter in audio. There are a lot of things that do not. Audiophiles for some reason are far more obsessed with the things that do not matter than the things that do.
God, grant me the expertise to recognize the variables that are not sensitive, the acumen to change the ones that are, and the knowledge to know the difference.
