Sony PUA 7 to re-wire or not

Dear @lohanimal: My take is that first find out if that tonearm is in good operation condition and for this you have to mount it in your TT and listening to it before you can or could think in a tonearm up-date.

Regards and enjoy the MUSIC NOT DISTORTIONS,

Good advice!

@lohamal

is it really the PUA 7 sold also separately or its twin brother but poorer fitted as standard for example in the PS X40 X50 X70 turntables etc.etc.?

I reckon it is the one fitted to the PSX 70 because the standalone PUA 7 has a slightly different arm base and I think a connector at the base. This one was sold to me on the premise that it was a PUA 7 but the wires are just hanging out at the bottom.

That's the reason that I need to get it re-wired.

I spoke to a good tech in the UK and he actually recommended kabob's super flex as it's the most flexible wire due to being in silicone.

The alternatives are:
Incognito - silver or gold that goes from the cartridge to the phono plugs 

Is the Ps X arm worth spending getting AN or say Ikeda wire?

it would be worthwhile to have bought the arm that was sold separately, the one supplied on the turntable and a version that resembles the PUA 7 but is not the exact same thing; construction tolerances and bearings have friction different, but perhaps you are already aware of all this.
If it were identical, it would not explain why Samurai electronics on ebay never manages to sell it for some time (a few years)
Now that you have it, fix it without getting too crazy about the choice of wiring IHMO
