Mikeyc8, try these...
1. Check your VTF (ignore the dial on your tonearm, if any, use a decent VTF scale). Excessively high VTF will cause a cartridge to sound as you described.
2. Reduce or even eliminate antiskate. Excessive antiskate sounds almost identical to excessive VTF.
3. Clean your stylus. Magic Eraser + dry brush. Nothing else.
4. Double check your cantilever alignment (not cartridge body alignment) using a good protractor.
5. Fiddle with VTA, though I doubt that's the main source of the dullness you described.
