I can say without a shadow of a doubt that the headshell provides at most 0.002% of the total audio output quality. So if you don't optimize that headshell your audio quality ceiling will be limited to 99.998%, and you'll be leaving that 0.002% on the table! Think about that!
Cartridge question
Going to replace the cartridge on my Dual cs1264 with a Vessel a3se.
My question is : Is it worth the extra money to replace the entire head shell even though my original wires look fine?
