At present, I'm using a Garrott Optim FGS. It tracks very well, handles warped discs with equanimity (unlike the Grado Sonata that preceded it.) It sounds very well balanced and leaves little to be be desired IMHO. Whether I play Rock, Jazz, or Classical, it delivers satisfying music. Since installing it, I never bother to look at cartridge listing on Audiogon anymore, so I suppose that says a great deal! OK, ONE improvement does come to mind. For a cartridge that sells for a grand, it is one cheap looking cartridge. That can be said of the Music Maker as well in my opinion.
