Soeaker cables technologic dilema…

BTW - how about NES-3001G with PTFE insulation? Worth considering against NES-3002G?

Quick question to the assembled:

What if the shield is grounded to soil, much like one's AC panel?
Good, bad, indifferent?

@milimetr - Not clear if you are talking about a double run of the 3005 in a bi-wire configuration where one pair goes to the MF/HF posts and one pair to the LF posts, or two separate runs with both wires inside of one jacket going to one polarity (i.e., + or -).

The only reason I would do a double run as described above would be to bring a larger wire gauge to the LF posts in a bi-wire configuration since connecting both wires in one jacket to a single pole would result in losing all the noise cancelling benefits of having twisted wires. 

@asvjerry - As discussed on the Supra Cable site, the screen shield in a speaker cable would most effectively be grounded to the amplifier chassis, or maybe to a univeral ground box. The negative pole at the amplifier would be a last choice.  From Supra Cables:

Earth/Screen connection. The earth conductor should be connected in the source end only (amplifier side) to:

1. Earth terminal at the amp (if available)
2. Connect to any of the amp chassis screws.
3. Negative speaker out terminal

@mitch2 I was thinking about separate runs (no bi wire) just to separate „+” run and „-„ run and lower interference of any kind between these two wires. 
Do you think that noise cancelation from twisting wires is wort to run them very close one to each other?

@mitch2   That was my thought, although I'd neglected to state such...
Not 'into' SOTA cables or speaker lines, due to their rather elevated price points and a plethora of IC's and lines in my system.
Spending more on such than what's been spent on the equipment itself here seems a stretch of logic...
Something pending on that Lotto win that's avoiding me at present. ;)

Carry on, and thanx, J
