Do you think the low-noise version is necessary? From their description, the regular and flexible ones (considerably less expensive than the low-noise) are good for "hi-fidelity professional audio"...
I've no idea, but was wondering the same. Maybe one of the more electronically astute around here will comment.
That source I linked is primarily focused on supplying lab instrumentation interconnects, where the bandwidth of the signal may be far greater than that of an audio signal. Pure speculation on my part, but low-noise requirements for some of those kinds of applications may be far more demanding than what we need. On the other hand, these aren't balanced audio cables, so any additional shielding may be useful.
But I've very rarely had RF interference problems with any of the miniature DPAs. That includes using just the integral mic cable, the DPA supplied microdot extension cables (which are rather stiff), or even using two cheap radioshack "mini-jack headphone extension cables" in series to extend the run from a used pair of 4061 I reterminated to a stereo mini-plug. The problem with that stop-gap "two headphone-extensions" solution has been occasional noise / intermittencies from those in-line mini-jack connections, rather than RF interference. So I clean them with Caig, re-gaff-tape them as securely together as I can, and do some listen-while-wiggle-jiggle testing before weekend festival outings to head it off, but replacing that run in particular is one of my goals in re-doing this.
The second, less-critical goal is to bundle the 6 long runs of this into one tech-flexed cable bundle (which should end up not much larger in diameter than a typical balanced mic cable), so that I only have that one bundle going down the mic-stand to 6 PFAs in the recording bag. Or alternately make a short 6-cable fan-out terminating to a multi-pin XLR at the top of the stand, which connects to a single run of cable multi-core cable down to another 6-cable fan-out to the PFAs in the bag. The same Mogami multi-core cable Len uses for the Tetramic should work nicely, which is very flexible and very small in diameter- not much larger in cross-section than the single DPA cable on each mic.
