Joseph Oberlander mentions a threshold of several percent "loss" for
audibility. This should be a clue that something other than distributed LC
is going on here. In terms of sheer signal level, a difference of a few
percent is completely inaudible. On the other hand, DISTORTION of a few
percent can be very audible.

I meant "loss" as in exactly that - as all signals degrade in strength as
the wires get longer. For most people, 1-2% is below their tolerance.
5%, otoh, most people can actually hear.
