A passive power cable cannot improve the power that is already on the line in series with the wall. Correct?
Although, a shielded cable might reduce the stuff getting in (shield connected to the plug at the wall) or going out (shield connected to the chassis), which might be a factor in the local environment with the nearby interconnects. The shielded cables with shield connected to both ends would be problematic (this is what I had). Correct?
So I want to ask how do people pick which shielded designs they pick for their gear. What's the reasoning for choosing one over the other? How do you know which one to go with for a particular equipment?
I want to know if there is any engineering drawback with either of these shielded cable designs for audio purposes? Are they more prone to picking up stuff? Is that why some of these premium shielded cables are advocated with a minimum or optimal length?
I see a few high end companies like Linn that advocate against using third party cables and just using their stock cables as it's voiced with them and they prefer that. I see the same with Naim. Forget expensive cables, but at the very least wouldn't top companies at least ship with stock shielded cables if they thought it made a difference at all, or a difference for the BETTER?
I still haven't gotten clarification on this topic to my satisfaction. I'd like these answered.
Lastly, I would like to see or do blind tests:
1) Is any difference noticeable?
2) If a difference is noticeable, which cable is 'preferred' or thought as the more correct sounding one?
