Well, I use a Shelter 901, and it took me forever to get it to sound good. You see, I was ignorant of the word, "compliance." So, after increasing the weight on the head shell (imagine taping two quarters to the cartridge) I finally got the bass and other things I knew the 901 was capable of. Tracking at 1.9 gm. So, make sure you get a cart with the correct compliance, you'll be glad you did. It will save you time and headaches.
