RE: power cord trick

I can only assume the silver plated strands are intended to tune the presentation of the power cord, perhaps due to the PVC dielectric which tends to sound a bit too slow and warm vs. a modern polymer with a lower dielectric constant. Also, a braided shield in addition to the aluminum/Mylar foil shield tends to darken the presentation and affect dynamics. The Black Mamba V2 only features a very thin pure copper foil shield which does not affect the presentation as much as over-aggressive shielding tends to do. Also, the polymers that Black Mamba V2 are not only selected for dielectric quality, they are also chosen for beneficial resonance control characteristics.

What's most innovative to me is the strand lay is optimized in order to avoid the detrimental affect of a typical stranded conductor with an ordinary strand lay. Another thing to note is since Oyaide's source of OCC wire was discontinued, they worked with another Japanese cable manufacturer to design a unique product that performs just as well as OCC according to their marketing information. The performance of the Black Mamba V2 proves its worth, as it's the best sounding power cord product I've experienced other than the VH Audio AirSine power cord.

Unlike previous Oyaide power cords featuring a thin copper foil shield such as the Tunami and PA-23 power cords, the Black Mamba V2 features a drain wire, which I assume is intended to be grounded at the AC plug, and left unconnected at the IEC end, which is what I chose to do. BTW, the Black Mamba V2 is a joy to terminate, since the low-mass dielectric and cable jacket are very easy to strip.
