Before changing carts, have you considered upgrading to the Signature arm? Also, have you optimized set-up? I made changes that, in hindsight, I wish I hadn't made before I learned how to really dial in set up. Use of the MintLP arc protractor and other things learned has made me realize that I couldn't have known how good some of my previous cartridges were. I wish I hadn't sold my Lyra Dorian, for example. Another cheap tweak is Mapleshade's NanoMount system, which I swear by.
My current cartridge is a Dynavector XX2MKII, which is all the cartridge I will ever need. My Sig. Scout has turned out to be a formidible record player, but not without optimizing set up, and a few upgrades. Just my opinion, FWIW.
Best of luck, and enjoy,
Dan
