I used some small O rings to secure the wire to the outside of the arm and there is a slack loop curling up from infront of the pivot to ensure there is no restriction to arm movement (The stock earth wire is still connected). Despite this wire being external the 50hz mains hum spike is lower than with the stock wire and there are less peaks further up the frequency range. Initial listening tests indicate there 'may' be a slight increase in detail but it's subtle. I will listen further and see if any sonic gains are worth the hassle of ripping it apart to rewire it. Then again why not just run it like this
As the wires are twisted what is the capacitance of the wires? I realise it is not a major concern for MC, but it is if you ever decide to fit a different type of cart. Also twisted or platting wires does reject well hum, but there is no beating decent shilding. What may be worth experimenting with for possible marginal gains (maybe) is twisted arm wires, but just connect to decent rca sockets, then do the rest of the run with decent well shielded rcas to the pre amp. This way the capacitance increase should be small as the arm wires are short and platting them with give an extra level of hum rejection. The rcas if well sheilded will not pick up any hum anyway.
