Cable for Tonearm/Turntable........

I have identified (with the help of you here at AudiogoN) that the hum I am hearing is caused by my current TT cable a Nordost Blue Heaven, I am told it is unsheilded .....My cartridge is a Helikon into an ARC PH3se.... Any suggestions for an RCA to RCA Tonearm/Table to Phono amp cable? Someone suggested Discovery.....????

Thanks to all!
