I recently bought a new turntable that came with the Ortofon 2m blue cartridge and I am not digging it. The upper mid range is pushed up and the top end is lopped off. I played about 50 lp's thru it and it's not changing. Yes I have it set up right. Can anyone suggest a replacement for this cartridge that is more neutral in the mids and doesn't lope the top end off for under $300 U.S. ? Thanks in advance.
