I believe it was Ben Duncan, years ago, who attempted to show that
speaker cables changed their delay characteristics with current. He set
up an experiment to demonstrate this, measuring frequency response and
delay with different currents - they did indeed change. Unfortunately,
the way he changed the current was by changing the load on the end of
the cable. It was of course this that changed the measured delay -
perfectly in line with established theory.


Indeed. Hence the footnote URL I gave in my first posting.

So no, Ben Duncan is not a reliable or trustworthy source.


I would approach this slightly differently. Are the *measurements* a
reliable source for the conclusions asserted in the pdf? My concern isn't
with the personalities, nor with the way any of us can make a simple
mistake.

Slainte,

Jim
