what cracks me up is that digital signal doesn't have loss or degradation like that. Additionally, I can buy copper or optical cable that has manufactured specs that are vastly in excess of the data rate you are getting even with 8k from any vendor, but sure, enjoy your special cables.Wait until they start about silver directional cables made by dwarfs during full moon...at $700 a meter.
My dad is a weirdo like that...30K in his system.
I always tilt him saying it sounds ok
