Jelco tonearm for Colibri Gold LW cartridge

It is not the mass of the cartridge that is critical but the complience of the cartridge, which is a quite different thing.

Van den Hul states pretty specifically on their website that the Colibris will work best with low to medium mass tonearms and that anything above 16 grams of effective mass is going to result in poor performance.

As such, I'd probably take that into consideration and look at other arms.

No, definitely not the ideal arm for the VDH Colibri LW. Try a high quality tonearm with a lower effective mass. We use a Colibri XGM (Gold coil/metal body) with a weight of 7 grams and the same static compliance of 35 Micron/mN mated to a tonearm having an effective mass of 12 grams. Even this arm has proven to be slightly heavier than ideal for the Colibri and as a result, does not track as well as it should. The exacting nature of the Colibri demands you use an appropriate high quality tonearm with initial setup being absolutely critical in order to reap the benefits of this special cartridge. The Colibri has proven itself to be the most demanding cartridge we have used in terms of initial setup and proper alignment parameters.

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.

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
