Re: Cable direction my oh my

["Jimmy Fowler" <jimfowler@prodigy.net>]

ahhh...reason and emperical data...music to my ears...

original message:
"With a good source, cable direction didn't make a difference in the
measurable jitter (fig.10). This suggests that the SV-3700—or any
poor-quality transmitter—reacts with the cable's impedance to create
jitter-inducing reflections in the interface. The directionality was
probably
caused by differences in the way the two RCA plugs were soldered to the
cable; any bumps or discontinuities in the solder or RCA plug will cause a
change in the characteristic impedance, which will cause higher-amplitude
reflections in one direction than in the other. These reflections set up
dynamically changing standing waves in the interface, introducing jitter in
the embedded clock. "

which means that they don't think it matters which way the cable goes!

One directional cables?  Well I'll believe it just as soon as I hear it.
