@1111art - You might do better to have KLE Innovations Classic Harmony RCA ($48) or Silver Harmony RCA ($72) plugs installed on the existing cables and you will hear an improvement.

Should I upgrade my TT wiring?
A local guy upgrades the wiring on older turntables for around $100.
I welcome opinions on if I might notice a difference. Pioneer PL-515 (my backup TT)
Here's what he does:
I use Mogami W2528 dual unbalanced cable soldered to Neutrik NYS352 Male RCA's. My cables are wrapped in durable heat, fade, and tear resistant TechFlex sleeving. The ground connector cable is copper tinned, flexible 20 AWG stranded wire soldered to copper tinned spade connectors and wrapped in Paracord.
