Just get $100 new cartridge and try it with it. We can't see or hear what you do. It's inexpensive experiment.
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.
