I suggest you test azimuth. Use the Cardas LP or similar with 1khz through the left and then right channel. Listen for crosstalk in the opposite channel. If one channel has more crosstalk, do the following. Using a hole punch, punch out a small round shim. Place this shim on the side of the cartridge opposite the weak channel.
Sorry, the Bordeaux calls must go now.
