So, just a bug to change something, I suggest you try a different cartridge.
Of the three items the OP mentioned, he said he's happy with the cartridge. Besides that, it's by far the best component he has in his analog chain. Even if he found something better, it's not going to be anywhere near its full potential on the entry level turntable he owns.
The Jolida JD9 is a noisy entry level phono stage that is not very well built. It's a decent entry into the world of tubes, and reasonably priced. I haven't heard the OP's phono stage, but owned a Vincent integrated and the build quality and sonics were much better than the Jolida products I have owned (JD9, JD9 MKII, Fusion preamp). A sideways move at best, more than likely a downgrade.
