I have Cat 5 V5 (although looking at the picture of theirs, my twists aren't as tight). Cat 5 is available on the internet for pennies per metre (I bought 2 rolls of 60m, although I ended up cutting them down a lot when I finished).
Stripping each individual wire is something which I did while watching a movie; it is pretty mind numbing and can be tricky at first. I used a stanley knife, and after not too long I was stripping them quite nicely.
Of course, this cable has very high capacitance (or inductance, I forget which), and my amp simply cut out after a few seconds when I had the original lengths of 3.3 metres in. However, cutting them down to below 2 metres fixed the problem; it could have been the inductance/capacitance, I am not entirely sure, but it works perfectly now.
ÿAll in all, I am relatively happy with my cable; it is definitely NOT a downgrade from the CHord Carnival Silver Screen, but I can't detect huge gains either. But at a fraction of a fraction of the cost for the Chord, you won't find me complaining...
And also, I have dressed mine in some 'expandable polyester sleeving' (ebay again), which smartens it up a little and means I don't have to look at the hideous grey cable all the time!ÿ
