Axle,
i dit have exactly the same experiences.Until 2 months iam allways against the voodoo of power cables.
As iam an electronic engineer, only few arguments could scrape my "bad" thinking about that.
A friens of mine, allways pushing me to try some cables, makes finally a bet for some bottle of wine to hear a difference.
Finally after MONTHS we make the experiment.
AND i was shocked what i have missed. And i was shocked because there is no real explaination(for me), only some arguments for the "technic".
Most of the explaination from the "manucturer" are bullsh..
But after severall trying forth and back and changing many cables and distribution blocks iam completly for this better power staff.
Still my brain is against it, but my ears are love it.
And we do makes some blind tests, so its not auto suggestions or what else...
Still confused
Robert
