I re-wired the arm with Cardas tone-arm wire a year ago. It was a nice upgrade with better dynamics, bass definition and smoother presentation. REALLY scary doing it though, LOL! Stripping those wires and soldering something that is so thin you'd swear it was a human optic nerve is NOT for the faint if heart! It all worked out in the end though. I ran the wires on the outside of the arm as obviously disassembling every part and pouring out the sand in the arm (and getting it back in) was out of the question!
I also replaced the RCAs in the back with newer ones as the old ones were pretty badly aged (the plastic portions all shrunk and cracking).
