AT-ART9XI Cartridge - Reduced Compliance

The XI will sound less warm, more transparent and neutral. Even in this video you can hear the difference.

I owned the 9 for a few years and loved it. works best with a low mass arm e.g. 9 grams or so. - your tonearm will work better with the XI.

as long as the XI keeps the squeaky clean colorful refinement of the '9, i could easily live with a more neutral sound.

Just installed an ART9XI and had owned the ART9 previously.
Running on a 9g arm with 64db and the sound is thoroughly enjoyable.  
Refinement, sound stage, transparency, dynamics and that treble !  
Sounds better than a $1900 LOMC from a highly respected manufacturer.  

edit previous post- make that a just installed ART9XA, not XI

I have no doubt that the XI is nice but listening more today of the XA, I would not want any more bass or warmth.   I suspect the XI has more of this. 
Everything sounds great on this cart. 

Is it that big of a deal to mod the class to see 64db?

per the Audio Technica web site you can multiply the 10um compliance by 1.5 to 2X to calculate compliance at 10Hz.  

This is the first time I have ever noted an manufacturer's compliance conversion formula in print.  

From AT:
To determine where the resonant frequency of a particular cartridge/tonearm combination will occur, you must first know a few things about your equipment. You will need to know the total effective mass of your turntable’s tonearm assembly, the compliance specification of the cartridge you are considering and the weight of the cartridge. Note that Audio-Technica specifies compliance at 100 Hz. Many resonant frequency calculators, however, use a compliance measurement taken at 10 Hz for their calculations. To determine the compliance of a cartridge at 10 Hz when only the compliance at 100 Hz is stated, multiply the 100 Hz measurement by 1.5 or 2.0. Once you have gathered this information, you can determine the resonant frequency using a resonance calculator such as the Cartridge Resonance Evaluator tool available at vinylengine.com. Enter the tonearm effective mass figure into the text box on .....

keegiam,
no problem, i was already aware of that info for my own calculations.  yes this stuff matters, nothing wrong with that.
enjoy the xa!  
fyi music direct shipped the same day for me, recieved it on the third day. 
peace.
