Jelco tonearm for Colibri Gold LW cartridge

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.

Folks, thank you for responses.
My budget is about $1500 +/-.
Speaking about SME 309 I guess mine not so clever approach doesn't get it to my heart just by the way it looks. I like more should I say conservative or old-fashioned style?
Ortofon RS-212D (cheapest I was able to find was $2375 new which is too much of a stretch for me) , AS-212S, TA-110 look good too but I couldn't find any. I found an older version - AS-212i (used) for $1060 and same new for $1545.
And Ortofon quotes an effective mass for these to be 3.5 grams! (without cartridge). If you can shed any comments on those, please...
Another one I was looking for would be Koetsu but I only found 10 inch, I only can accomodate around 225 mm.

The stated 3.5grams total effective mass for the Ortofon TA-110 is not correct, it is more like 19g. You are quoting the mass for the arm minus headshell, which is rather heavy at roughly 16g +/-.5g. All current Ortofon arms are much heavier than ideal for the Colibri LW in terms of total effective mass. Better to stick with a used 9g effective mass SME 309 or 9.5g effective mass SME M2-9.

Sorry for the pedantry, but both static and dynamic compliance could be specified with units in "Micron/mN" or "cm/dyne". They are equivalent units. (micron = .0001 cm; dyne = .01 mN.) What's unusual, I think, is that vdH use "Micron/mN" and give the static value, whereas almost everyone else uses cm/dyne and gives dynamic value. vdH also specify output at something like 5.4cm/sec stylus velocity, whereas the rest of the world use either 3.54 cm/sec (the old standard) or 5 cm/sec. This gives an optimistic idea of cartridge output, if you compare their raw number in mV to that of most other cartridges.
