You say I'm wrong but you admit you don't know the difference between the two!
Audiophile grade caps are made to higher tolerances but if the circuitry is not designed to take advantage then there is no point.
To be honest audiophile gear is mostly marketing BS anyway, the prices charged are simply not reflective of the quality of the equipment. Eg Several of the big names have been caught re-casing everything from Oppo (very good but affordable brand) to lg bluray players and tweaking the firmware slightly is the only real change when you open them up.
