Cable Recommendations for Entry Level

I am a newbie to this forum and starting to learn just a tiny bit about better equipment. I just upgraded my junky old technics tt to a new REGA RP-1. I have some old JBL 4312A monitor speakers and am currently trying to get hold of a NAD 3020A integrated Amp. My CD player is nothing special. Just wondering if anybody can recommend a reasonable step up from my old radio shack speaker wire...
