best synergy cart with romeo arm

hello i wnat to ask mr. twl about synergy cartridge/arm.i have the audiomeca romance/romeo turntable and i wonder if i can use the shelter 901 cartridge on this arm.Th e arm is unipivot but has a small ring that you can use at the base of the arm and then works as a semi unipivot.The effective arm mass is 12g.
No problem. Right on target about resonance frecuency. The 901 is a little on the hi-fi side, I don't recomended. If you want a Shelther is better that you could go for the 90X.
Regards and enjoy the music.
