your points on connection quality are well taken Albert - i do clean connections (though probably not as much as I should given most of my equipment is a few years old, or older). I understand conductivity, and impediments to it such as oxidation and poor fit. Mostly I can hear distortion and noise that appears when there are problems. I don't accept your "direct vibration pathway" point however.
My skepticism, and amusement, relates to the discussion of outlet covers and how tight screws should be on them . . . although if one of my outlet covers began to rattle because it's too loose, I may take an interest in it.
Maybe I just wish my system was to the point that it was down to the outlet covers for that last little bit of sonic advancement. Then again, I think I'll spend my time just listening to the music.
