Bill,
I'd say the cart is too good for the table & tonearm. I would really consider upgrading the Performance to another table (not necessarily Clearaudio). Which one depends on how much cash you are willing to throw at it.
There are many choices : SME, Avid, TWAcustic Raven (which I use), Notts Analogue, Verdier etc, even VPI ;^)
The choice of partnering tonearm is also vitally important. I cut out the intermediate choices and went for the Graham Phantom. SME V is also a popular choice if you prefer gimballed.
