Wes -
I've been doing some research on balanced cables and I haven't had a whole lot of luck finding what I've been told is a true balanced cable.
You're probably asking what I mean by "true balanced cable." Here's what I've been told. Some systems have an active differential circuit that, for the circuit to work correctly, needs three conductors - Pos, Neg, and Neutral - in addition to the shielding. The circuit monitors the Neutral and adjusts the signal based on the feedback. The B&K equipment I'm purchasing has a Differential Balanced Circuit.
So far, I've only found one cable supplier, Audioquest, that has a 3 conductor balanced cable. I've found lots of options for a two conductor cable with XLR connectors. However, they use the shield as the neutral leg - which I've been told doesn't work as well.
Depending on your equipment - this may not even be an issue. If you find another, or other, supplier(s) that have a 3 conductor cable please let me know. I haven't purchased the Audioquest yet because they are expensive. However, I'm wondering if the old saying - "you get what you pay for" is true in this case.
Good luck.
Paul
