Grounded Speaker Cable

@rib61, This article just came to mind an overview of audio system grounding and interfacing see here.

"likelihood of this ground wire improving sound in a residential setting appears to be minimal"

not minimal, NONE, no need, NADA, in fact it ADDs potential for problem.

You cannot solve a non-existent problem.

Read all 200 pages .put some science behind audio equipment and very informative on published reference.  Very helpful.

User @nutty has these speaker cables. He has both the SP12s and the SP14s and he said he likes the 14s much better. Maybe he'll chime in here.

The 14s are also better in their inductance measurements according to Cap. If you like the 12s, the 14s are just sweeter sounding. The new interconnects are also worth considering. I really think Cap has knocked it out of the park with these new cables - maybe he could send you a pair to demo
