Bought a new Shure M97xE cartridge. Asked the shop owner if he could mount it. He did. And all was well. Until I bought a different turntable and put that headshell/cartridge on that turntable. Right channel was nearly nonexistent. Original cartridge sounded fine. So I make my first mistake. I swap the cartridges. Now the Shure sounds better, but the soundstage is definitely shifted to the right. So I order the Technics overhang gauge. It arrived today. Mistake number two, I line everything up as best I can and try again. The stage is now a bit more to the left, AND sounds like mud. I have to crank the volume up way more than normal to get the same level.
