Yep, just went and bought a high quality local version of Bix's cable "on approval" - a 5 metre full-length replacement, so no in-line joins, and for the same price as Dick Smith's (link in my last post) short "cheapie". Can take it back if it doesn't do the job.
As I write this it is evident that I don't need to take it back. The picture is perfect.
Mr Smith will get his back, though
