I think the product code you quoted should have been 2D4P5IPV3B.

Personally, I've never used teflon sugared Cat 5e in my amp or pre-amp. Only the run of the mill stuff (such as this) left over from LAN cabling works at an old worklpace. And I've still plenty of it. Huey knows whether what I have is the Clipsal stuff (unlikely) but it isn't that disimilar in specs. If you go and have a hunt in the skip bin of your local data/telecommunications/office equipment installer I'm sure you'll find loads of the stuff for next to nothing.
I honestly fail to see (hear?) how a wafer thin layer of polyethelene could be audibly different to a wafer thin layer of PTFE over the same length of 24 gauge copper wire..........but then I'm rarely credited with an overabundance of imagination either.
If you are besotted by the idea of teflon coated wire then grab some of this second rate poly coated gear, strip the poly off it and wrap the naked wire in plumbers tape (admittedly not practical for speaker wire). Or do what I do in hookup situations and just use shoelaces as insulation.....
