https://www.analogplanet.com/content/uni-din-versus-l%C3%B6fgren-b-just-clarify according to Mikey's findings, Stevenson alignment has the most distortion most of the time. Unless you're playing very long records you will experience the most distortion near the end of any album side.
looking for advice to mitigate inner groove distortion
I currently have a Nagaoka MP200 on a rega P3 with all the groovetracer upgrades (including counterweight for better tracking). I've calibrated the cart using the Stevenson method but I am plagued by inner groove distortion. I'm considering getting a MP500 with the line contact diamond to help. Is this a good idea? I know IGD is part of the deal with Vinyl but I get bummed out every time the last song on the record comes on.
