What turntable cartridges have you all found to be a good pairing for your Fisher preamps? My MM cart is in need of a new needle and was thinking about trying something else out. Not sure if I want to stay MM or try a HOMC or LOMC w/ an SUT. I realize turntable and tonearm are factors in the equation too, but not so concerned by them at this point. So what have you found to be a good match?
