How do you explain audiophiles to your friends?

I’ll start.

I tell them go to their local hardware store and get two gallons of white paint.  But in one gallon add a drop of eggshell colored paint.

Paint half a wall with each.

A person who thinks they might be able to see a difference is a budding audiophile.      The person who sees a night and day difference is THE audiophile.
