Linn Sondek phono cable


I own a Linn Sondek, ekos arm, arkiv cartride & lingo power supply.
I need to make the phono cable longer and need to know what type of wire they used. My table was produced in 1988.

Thanks for any responses.

Remember that the tonearm cable is part of the Linn suspension, therefore, extremely thick and stiff phono cables need not apply.
I have had good luck with the AQ leopard...might also consider crystal cable as they are flexible and very low mass...
