Hi all,
I experimented with a number of different cables, made a decision, and buil=
t the mic cable. Here are the results. You can check out the finished assem=
bly here:

I was looking for a solution to get from the "Y" up to the microphone with =
the least amount of mechanical coupling. Below are the cables that I worked=
 with. I rated them 1 to 10, 1 being poor (high coupling) to 10 (high isola=
tion). The Mogami 2697 was by far the best for isolation in my tests.

Thanks to Paul Thomas for initial suggestions and brainstorming on the appr=
oach for testing these.  Basically, I tie wrapped pieces of all candidate c=
ables to the base of one of my mics and figured out a way to consistently w=
hack them and observe approximately how much energy coupled by using the VU=
 meter on my SD 722 and listening through headphones.

Thanks for your suggestions and assistance. Anthony's lead yielded the thin=
 Mogami that worked best here. Thanks to Robb Nichols at Aquarian Audio for=
 getting the nice custom Gepco cable to me. Paul Thomas obtained the cool c=
loth covered cable from k-Tek.

I'm looking forward to getting this new cable assembly out into the field!

All cables are shielded twisted pair except the "K-Tek" cloth cable which i=
s three twisted wires, a highly flexible shield, and a cloth jacket.

The (1-10) rating is based solely on how well a short length of the cable b=
locks mechanical energy.
