Ortofon 2M series
Anyone have an opinion on this series of cartridges? I'm about to make my first big cartridge upgrade (I purchased a Pro-ject Debut II three years ago and moved up from the stock Ortofon to a Grado Green about two years ago - I also have a NAD PP-1 preamp) and I was interested in spending $200-300 on a cartridge. Obviously I've been looking at the usual MM/HOMC suspects (Grado, Sumiko, etc.) but I still haven't gotten the acrylic platter upgrade for the Debut, so I'd have to do that before buying a MC cartridge.
Anyways, after all that long-winded explanation, any thoughts on the 2M series? I know the Black is a significant upgrade from the others, but how do the lower models differ from cart to cart?
