Out of curiosity, I just stripped the jacket off of a cheap microphone
XLR cable that came with an Audio Technica ATR2100 microphone. There is
a second jacket inside the outside jacket. If the cable is the same as
the one at the link below, the inside jacket is a "Conductive PVC Shield."

How effective is the conductive PVC shield? I assume it's crap, but can
it be quantified? Is it 50% as effective as a foil or 100% braid shield?
30%? 80%? I used one of these cables in a pinch and was surprised when
there was a little noise in the system. It will be interesting to see
whether a real cable will clean it up.
Bonus question: What's your favorite bulk XLR mic cable (other than star
quad types?)
