I have the standard arm. I actually had my table professionally setup today. What a difference! He did say that my cartridge had quite a bit of tracking error(distortion) that he tested on a test record and analyzer. He actually showed me the tracking distortion. He said I definitely should get the antiskate device. I told him that VPI does not recommend the antiskate. He said that is total hogwash and he visually showed it to me today. He said I could apply more vertical weight to the cartidge but that it was just a bandaid until I address the problem. He also said that moving magnet cartridges actually track the record better simply by the nature of their design and are especially great for large orchestral crescendos. All I can say is that my turntable has never sounded better. I cannot believe it! He also said that when I get the anti skate, he can really improve the performance of my table. He said it is all about setup. Now I believe it. He has been doing it for 40 years and I can tell you he is damn good at it. Gosh, do I love vinyl! I learned a lot today!
