You need a cartridge. If you have only MM level input, then go to at least a Dynavector 10x4 high output MC. The Linn K9 is a low priced Audio Technica cartridge labled for Linn. It has no place in a system like yours. If you can afford it, then get a MC step-up device and go with a low-output MC cartridge like a Denon DL103 or Shelter 501. Actually, depending on how much you use analog, your whole analog rig could be upgraded, considering the high quality level of the rest of your system. But, definitely at least the cartridge. That is the weakest link.
