Recommended coax cable for Metrum Octave


I'm getting an Octave to go with my SB Touch and need a coax cable to go with it. Since my cabling is Purist Audio, I was thinking PAD Genesis, but Cees at Metrum provided the following "specs" which the Genesis does not fulfill (#2 & 3):
1) 75 Ohms
2) Teflon isolators for shield and center conductor
3) Both core and shield should be copper silver plated

I'm thinking a VH Audio Pulsar Ag would fulfill this. But would appreciate hearing what has worked well for you.

Thank you!

Digging around forums I found DH Labs D-75 terminated cable, highly praised for the money ($90!!), and complying with above spec. Anybody tried it?
I am using Transparent Reference with mine, may well be the best but list price is higher than the cost of the Metrum, I bought mine on ebay. Clearer Audio Silver is also very good but not cheap either; paid around $290 for mine new with shipping and latest WBT plugs.
I changed the RCA to a 75ohm bnc on my metrum, so now bnc from jkmk3 to metrum. A worthwhile endeavour.
The Wywires LiteSPD spdif is very good with the octave. It's terminated with RCAs, but they are Xhadows and legitimately 75ohm, so there is no need to modify the unit to take BNC, imo.
