Grounded Speaker Cable

I've never heard of such a thing. Who makes this cable? It sounds like it could be an issue with some amplifiers that do not share common grounds.

Audio Envy makes it. It's their SP14, which is the successor to the SP12 that I'm using currently.

I, too, am skeptical about this wire. I would ask the manufacturer for proof of concept before buying.

I've never heard of such a thing. Who makes this cable? It sounds like it could be an issue with some amplifiers that do not share common grounds.

It seems like it could be a problem with a floating ground, it definitely wouldn't work with one pair of speakers I own.

I couldn't find a reference to that cable, but guessing it's shielded and that's what the ground is for?

Here's an interesting article on the grounding debate that may explain it:  Grounding and shielding: No size fits all

Personally, I've been eyeing Analysis Plus' speaker cables because of their approach to shielding.
