Ethernet Cables - what are you using and why?

Melco C100 ethernet cable. It was a large step up from the Nordost Heimdall 2 ethernet, at 1/5th the price.

It uses a floating ground at one end, to drain noise away from the source component. So its directional and using it in the wrong direction is very audible.

Why 8.5 feet and not 8, 9 or any other length. Did you test different lengths to come to this or was it an arbitrary length you stumbled upon?

There are resonance and reflection points with digital (and power cable) lengths, more so than with analog signal cables. Knowing what those lengths are is the trick.
