I think the simple answer to "Does this have implications for audio cabling" is no. I didn’t see anything in the presentation that would make a whit of difference anymore than it would to television, refrigeration, lighting, power recliners, coffee machines or any other electric devices in your house.
For those that continue to believe electrons, electric charge, carry the energy from the power plant to our homes would be living in the dark if true.... The energy generated at the power plant would never leave the plant. It is impossible for electrons/electric charge to jump across the the gap from the primary winding to the secondary winding of the step up transformers at the power plant. But yet the electrical energy that is generated at the power plant is the same electrical energy that enters our homes. The electric charge never gets past the primary winding of the step up transformers at the plant. The electric charge pretty much just vibrates in place and moves as slow as cold maple syrup in the closed circuit loop.
It is impossible for those stunk in the belief that an audio signal flows back and forth in a conductor from a source to an amplifier or to a speaker to understand how an interconnect or speaker cable could possibly sound different from one another. But yet for many of us they do...
