Which tonearm cable?

I have two of the ones listed here and find them to be very good and better constructed than many far more expensive ones. He offers money back if not satisfied.

The Phonocable is probably the most important one in the whole System. Nowhere else the signal is so small, can be influenced so much (it should be shielded) and nowhere else the loss of information can be done faster (material of connector, kind of wire from the ability to transfer signal).
Some time ago there was a special made rewire kit from Incognito for Rega Arms available. It is not so expensive and the sonic jump compared to stock is really huge. Try to find some information about it.

Not sure if I agree with my friend Syntax: important ok
but 'most important'? Anyway he is not very specific. You have basicaly the choice between the silver and the copper wire.There are people who swear by silver but also those who hate silver wire. Then there are huge price diferences
inside and between both categories. I assume that you are not willing to pay $1000 for the wire meant for a tonearm of, say, $300? The (huge) advantage of Rega is the construction which allows for an easy access to both: the tube and the collar. If you are skilful with the soldering iron you can do this job yourself. There is no cheaper way
to my knowledge to rewire an Rega tonearm. You can find all the needed info on the internet.

Thanks Guys,

Very helpful comments. I agree with Nandric. I don't think that spending $1000 for tonearm cable is justified but I have seen a few cables around the $300 range. The argument over which is the best wire, copper or silver still rages on and I am not yet convinced that either one has an advantage over the other. I think I'll have a look at Stanwal's suggestion and if that is no good then I'll keep looking on the internet.

Purist.
