I have seen quite a few posts on here-both good and bad--regarding certain cartridge combinations and the problem of no VTA on Rega tables. In my case, I am using an Ortofon 2M Bronze on my RP3. My question does regard proper VTA in a case where it is perfect on 180-gram or 200-gram vinyl, but just a hair off on the 150 gram (normal) LP's. Which should one adjust for? What you have more of? Also, does anyone know of a list of cartridges that do demonstrate proper VTA with Rega tables? I should add that azimuth is spot on as are both points on a Hudson Protractor. Thanks.
