clearaudio champion w/ unify but what cartridge?


i'm getting ready to set-up my new clearaudio champion with the carbon fiber unify tone arm and i'm looking to get some cartridge recommendations. I'm moving up from a MMF 2.2 with a blue point no. 2 and in fantasy land i'd like to end up with a stradivari. but to start what would some good matches between 300 and 1000USD? Or if anyone has a used symphony you'd like to sell me?

A Cearaudio Virtuoso (Ebony) Wood Cartridge came with my Marantz 15TT. When the tonearm proved to be defective I was sent a new TT. The cartridge is Black and Silver, unlike the ebony black I originally purchased. I have noticed a sound difference. The Ebony seemed clearer. But then again the tonearm proved to be defective. I do not know if the "Ebony" should always be all black. Does anyone?
is the marantz tt15 unify arm the same as the satisfy carbon fiber arm on the emotion cmb table? are all unify arms sensitive to vibrations? the unify fluid arm on my michell reference hydraulic transcriptor doesn't seem to be overly sensitive to vibrations.

I had a Clearaudio Stradivari MC on my vintage Clearaudio Revolution Turntable. Sound is gorgeous. Synergy is a key. You will want an amp, a phono pre and wires to do it justice. But the champion is a worthy table! Have fun!
