Funny, I was thinking about the same thing. I've got the Peformance DC also, and wondered if the TT5 would be over kill. I'm not crazy about jumping up to the Ovation for another 3k with about the same tone arm I have on now.

Thinking about getting one with a Performance DC, what cartridge would work with it? Compliance and so forth. I Have Ortofon Quintete Black and Sumiko Blackbird High output
