“If it’s just audio, no problem. Check out Belden 1353A. It’s really a Bonded-Pair Category 5e patch cable, but it’s in the audio section of our catalog! It’s the best audio cable we’ve ever made.”
Belden 1353A is simply one pair, 24 gauge/2 conductor, each conductor a stranded wire with 7 32 gauge leads, not 4 pair utilized in ethernet cables.
“Belden Brilliance 1353A, a new Cat 5e digital audio single-pair cable, is ideal for use in professional and commercial audio applications. Since it is essentially ‘single pair-Category 5e,’ tested to 100 MHz, its low capacitance (15 pF/ft, 49 pF/m) makes it excellent for both analog and digital audio.”
I’m not speaking to interconnects in my original statement, but shielded cable for ethernet usage. If you really want to test out why I use STP for my ethernet, get a pocket AM radio, turn it all the way past 1600kHz and get close to an UTP cable that is live, and then do the very same with STP. You’ll find out really quick that egress from the noisy environment it presents isn’t something you want close to any low level signal cable. Secondly, if you use a switch with a wall wart for example, it has no reference to ground if UTP is utilized. This is why I use STP from my source to the switch. It prevents egress, and gives a ground reference to the switch. (this is not accomplished through UTP as the unused pairs are decoupled and not attached to the ground plane of the switch itself, however the shield is)
The primary focus of the article you have referenced deals with shields in the audio spectrum, and it doesn’t matter if removing one end of the shield creates a filter at 100kHz, since that is many times above the audio spectrum. It’s the way loops are dealt with in analog audio cabling utilizing shielding, and the cable is still Faraday’d if one side is lifted.
“So, instead, most installers resort to the next best thing- cut one ground. That instantly solves your ground loop problem, but which end do you cut? The answer is, leave the source (the low impedance connection) and cut the destination (the high impedance end).”
