Well, a grinding noise is not good. It is possible that you damaged something. You may be able to look at the stylus under a 20X, or higher, magnification to determine that. Of course, if the cantilever is is bent or the body is riding very low, then you already have the answer. The Grado is a very nice cartridge, warmer and fuller than the AT. Very pleasant and easy on the ears. The Red is an even better choice for, predictably, more money.
Your sights may be set a bit low though. IMHO to get the performance of the 2002E (yes, I owned one back in the day) you will need to spend $150.00 to $200.00, which I suppose, adjusted for inflation, is a bargain.
