No thanks, However I will repeat the test today, and see if its possible
to measure any difference.


Given the capacitance Arny quoted that would be a -0.1db at 20k
compaired to 2k, I agree that you may not be able to hear that, but I
wonder if the 9deg phase shift would be audible.

It's not, and there's a £1,000 guarantee on that! :-)

This is based on a 5k source impedance which is about what my phono is,
you may (with some justification) argue that thats higher that it would
be with a competently designed SS source, but thats what I was using
when I heard the difference I described.

Let's be clear about this - I don't believe that you 'heard' anything
with a real physical existence. A high output resistance can certainly
introduce a noticeable treble droop with a long run of
high-capacitance cable, but what you're describing should be barely
measureable, and certainly not at all audible.

OTOH, I can of course easily demonstrate dufferences between two
cables, which you will easily hear - even though I won't actually have
switched the cables....................
