Discovered a stash of these new and unmounted A90 cartridges in the warehouse while looking for another piece of gear. Guess this happens when I don't get out of the shop much:) These are outstanding cartridges made with a revolutionary new manufacturing process at the time. Still unique in the cartridge world as far as I know.
It is a strong, dynamic and very musical cartridge. Not sure there is a cart at this price that comes close to the A90.
