Have just installed my shiny new AT-OC9 as supplied at a great price by Dave C (thanks Dave).
Even though it's currently in a stock 1210MK5, save or a record clamp and a Sumiko headshell, and even though I can't get the VTA right until I have a headshell spacer and my new, light AT MG-10 headshell, it's still sounding pretty darned good!
I'm now toying with whether to sell my DL304 or keep it mounted on a spare headshell as a spare....
