Jelco tonearm for Colibri Gold LW cartridge

To Chris74,
Hi
How is SME m2-9 in your opinion, it's effective mass I believe is about 9.5 grams?
Or should I look at something else?
Thank you

"Actually the masses of the cartridge and tonearm are both critical.

Their combined mass, in conjunction with the cartridge's compliance, determine the resonance frequency which in turn affects overall performance."

Agreed, that is absolutely correct.

Yes, 9.5 grams would be a better match, however I would stretch the budget a little and go with a SME 309. The Colibri ideally should be used with the highest quality arm possible.

I thought the OP was under the impression that if the mass of the arm was high then the mass of the cartridge must also be high; that was why I suggested that the compliance was the critical factor. If the compliance was around 10, the a 25 gram combined mass would be all right. As the complience is 35 according to posters then the cartridge would have to have negative mass to work ideally.

Stanwal, VDH compliance rating is a bit unusual, they express compliance specification in static compliance (Micron/mN) instead of dynamic compliance (cm/dyne) like most mfg's. So, in more typical stated dynamic lateral compliance terms it is more like 18cu. (approx.) even this figure is subject to scrutiny as each Colibri is hand built and as a result these specs may vary slightly from cartridge to cartridge. Not to mention the fact that this compliance figure may not reflect a typical 100Hz measurement. The poster could possibly contact VDH directly with his cartridge serial number though to try and verify compliance stated in dynamic terms.
