How do you reconcile this 'no difference' claim with your notion that a
clean plug can affect sound?

What would cleaning a dirty plug do to the sound?


You are confusing mains power connectors with audio interconnects, it was
the later about which Graham referred to cleaning the plug. Poor contact on
audio interconnects (and on switches carrying audio) can adversely affect
sound quality.
