Hi
It is true that capacitors can have nonlinear effects.
In most cases, the design is such that these effects are
vary small and only in cases where the capacitor is used
as a filter parameter that has a sharp cut off, does
this have measurable effects. This means that blindly
replacing all the capacitors is just plain silly.
Speaker wire is another interesting one. All wire
has impedance ( DC and AC effects ). No wire will ever
be the right impedance for an 8 Ohm speaker. Different
speakers are effected differently by the speaker wire.
I've done some AB test with wire and for at least two
speakers, I looked at. I could hear no difference between
6 feet of 12 ga. appliance cord and woven special speaker
wire. I doubt my hearing is good enough today to repeat
such test but at the time my heard was better than average,
being able to clearly hear TV horizontal outputs from any
TV across the room.
