I was using a Contrapunkt C a year ago. I had a couple of more expensive Benz cartridges before that, and was looking for something less polite and with better tracking on a couple of older records. It was lively and dynamic and never had any tracking issues. I still have it and will use it again if the London Decca cartridges I have fallen in love with ever fail (a matter of time, I know!)
