So I've been running a plain old DL-103 and for the last several weeks a Dynavector 20X (lo). I really don't think the Dyna offers any added detail or resolution, and I have it loaded down at 100 ohms. Any higher and I get sibilance in parts where there should be none. What I am really impressed with is how much less noise the DL-103 picks up. Once even VG condition vinyl has been through my cleaning regime the DL-103 is just a lot quieter. I mean it obviously can't do anything for deep scratches, I am talking about surface noise mostly.
I just ordered a DL-103R, these Japanese broadcast cartridges. I will keep a high end MC for audiophile vinyl that is naturally quiet.
