ive always been slightly baffled that people run actives when not stealthing. unless u are clamping on, it really makes no sense, and its got to be better to run the caps rigth on the bodies. arent some active cables un-balanced? id like to hear some spec'd details of the difference of running a 5 meter cable vs. having the capsule on the body. my gut feeling is that its not the same.
We did some testing a while ago and didn't hear a difference. These were pure silver cables(Vampire) against the KC5s. Cable noise is a lot easier to make with the actives. If you don't know what I'm talking about, set up your rig at home, put on some cans, grab the cables and give them a shake. Yuck! Yeah, it does also happen with balanced mic cables but not as loud as actives...
