Another Cart upgrade thread?

Yep.

I have a clearaudio concept MC that has been retipped by Andy at needleclinic. He did a fine job btw. The cart is really the only holdover in what has been a near complete system overhaul within the last year.

My system now:

Nottingham 294 with Notts 12" arm
Musical Surroundings Nova II phono Preamp
Nuprime DAC10 (line pre and dac)
Van Alstine Synergy amp
Philharmonic BMR speakers
Rhythmik E15 subs x 2
Clear Day double shotgun speaker cables
Audio Art IC3se ic's
GIK room treatments

The system has never sounded better and the concept MC is no slouch. So how much better would one of the following carts be (or would they just be different)?

Audio Technica Art9 - same price range as the concept MC but it's the darling of the day and supposedly competes with carts 2 to 3 times it's price

Charisma mc2

Charisma reference 1 or 2

Kiseki blue NS

Ortofon Cadenza Bronze

Clearaudio Charisma V2 MM - $2000 for an MM? My curiosity is peaked

Let me stress that I do not want in any circumstance to sacrifice natural organic timber and warmth for analytical scrutiny. Detail and warmth are both nice but I'll take a little extra warmth and a little less detail if need be.

So, how much improvement to be had with carts in this price range?
