That's for the link Steve, will check that out! My second arm is a Trans-fi Terminator, which is also a semi-DIY solution that punches well above it's weight from the UK!
@rauliruegas, thanks for those rewire links. I'm wondering how much benefit I'd get by rewiring the arm wands without rewiring the body as well. Either way there would still be several plug connections in the signal path. As an experiment I may wire up some tonearm wire direct to a couple of RCA plugs and run that up the outside of the arm to see how much of a difference it makes.
