While I spend a lot of time here I also have a life that sometimes takes precedence

Sometimes it's best if people try things for themselves specially when gaining experience is relatively cheap as in this case. This Furutech wire's double shielding pattern is similar to VFD (variable frequency) wires I've experimented with in the past. VFD cables were designed for motor control applications in harsh, noisy industrial settings where voltage spikes are also common place, typically this isn't your home environment. I'm not technically versed like Dave C what I know is what I learn from experience and I find that power cords made from VFD cables harden the sound and have a hifi quality to them. I haven't tried this particular cable but I'm not a fan of double shields for audio, I find that these designs trap as much mains noise as they're trying to block externally. Of course a lot of it comes down to system resolution, one might not hear a VFD cable's issues with a system which is already hard sounding.

(Edit, just noticed your comment on the cable design) PS- Here's a picture of a basic VFD with a foil and braid shield, what's so different? There are 3 conductor types and if you google VFD cables you'll find some with similar winding style too. Hey if you're happy paying a $1000+ a piece for industrial wires Blimp, be my guest.
