I've got a vintage turntable from the 70's, and It has an original era headhell with original cartridge wires. I replaced the cartridge, but left the wires (two wires even broke and separated from their prongs, but I was able to re-solder them back on). The audio quality is great but to be honest I don't know whether or not it could sound better. Is it a good idea to replace the headshell/wires on this vintage machine?
