Lowest distortion will be at the two null points - where the stylus is MOST tangent to the grooves. This applies to ALL pivoted arms! The emphasis on the left channel could be a problem with the anti-skate mechanism on your tonearm. Try adjusting it for more or less force while listening.
Dynamics varying with track position.
I’m finding that dynamics and timbre improve as the cartridge moves toward the inner 1/2 of the album. Running a DL 103r. Aligned on my 303 arm with Regan paper protractor. Also a slight emphasis on the left channel. Tried realigning/ checking overhang and I’ve heard no change. Also checked the alignment with the Ortofon guide. Any one have a thought on the cause or remedy for this?
thanks.
