Cartridge for Clearaudio Concept TT

I've had a Clearaudio Concept TT for a few years.  It came mounted with the base Clearaudio Concept MM cart.  I'm starting to look around at an upgrade and I'm looking for suggestions.

I'm using 1980's Yamaha SS gear with a pair of Klipsch Chorus II speakers.  I listen to Rock, Blues, and Jazz. Good midrange and bass slam are more important to me than top end sparkle.  That being said, I don't want a veiled/dark sound.

My local dealer is suggesting the Dynavector 10x5.  I've never heard this combo, but have some reservations based on reviews of the cartridge that I've read.  It does have some great reviews as as well.  This is especially true when talking bang for the buck, but it looks like this cartridge has jumped in price in recent years.  Maybe that is not so much the case anymore at the $650 price point?

Any thoughts on the Concept w/Dynavector 10x5 combo?  I'm trying to keep the price below 1K so the Concept MC would be as high as I would want to go.  My Yamaha C-60 preamp has 100 and 1000 ohm setting for MC carts if I go that direction.

Any opinions would be appreciated.
