any time you surround conductors with a braid like that you add some shielding (conductive braid, not just any Techflex). The question is, is it needed?
speaker signals are MUCH higher voltages and currents than video or audio signals, making them much less succeptible to picking up radio noise or stray video signals. Power cords could be of some concern, but the speaker wire and power wire would have to be side-by-side for a significant length in order to pick up enough hum. Simple 6" of separation or crossing them at an angle is enough to not even worry about it.
That all being said, I made some video cables with that Chrome Techflex for a client and they looked awesome!
But for the most part, I wouldn't consider the chrome for shielding. If you like the look, great, but it is likely not necessary.
