[sdiy] "Time Winding" in Audio Cables ???

Thanks everyone, for confirming my original belief that this time-aligned 
cable stuff was just so much worry over nothing noticeable. I knew about 
the capacitive low-pass filtering action of cables, and I knew about 
reflections that can occur (especially at RF frequencies), and I knew about 
signal losses due to resistance and other factors. I had just forgotten 
about the difference in propagations speeds for different frequencies. Even 
if there is a difference, I just couldn't imagine it being enough to be a 
noticeable problem for a 1 or 2 meter shielded patch cable.  :)

Out of curiosity, does anyone have any idea what amount of arrival time 
difference there might be, between a 20Hz signal and a 20 kHz signal, over 
a "typical" mediocre-quality 2 meter shielded patch cable? I imagine it's a 
very small difference, but does anyone have any actual stats regarding how 
small?

This might be a good question for Magnus. He knows everything.  :)

thanks,
Glen
