Denon DA 307 and DA 309


Hi, anyone know the effective mass of these tonearms?

Cheers

@ihcho When DA-401 was released it wasn't a problem to buy additional headshell for this model. I have 3 original headshells for this tonearm to swap cartridges. The shell is super lightweight and this is why it's not a regular headshell. Now search for the headshell and buy it! 
It’s been just a couple of days sinceI got the turntable and have had no luck to find a headshell for DA-401 yet. ;-)
Let me know, just in case, if you think keeping three headshells for this tonearm is too much for you. I have DL-103R and Ortofon MC20 super but it looks like this tonearm may not be able to work well with them. Will see.
thx
There is no horizontal movement, if you engage the antiskate yes it moves outwards as it should, the tonearm hasn't been overhauled.

Many thanks



Anybody has used both DA307 and DA309 arms and has opinion on both?
It looks like DA309 sells at around $100~150 more than DA307. Is DA309 worthwhile for $100~150 more if somebody has a choice between DA307 and 309?
Thanks in advance.
This is not related directly but Thursday I finally finished setting my vinyl rig, adjusted the XSV3000SP VTF with brush to 1.5g and tested, it tracked with no issues, finally used the Hifi news LP and there was some unwanted noise on top of the tone when playing the tracking tracks ... Increasing the VTF to 2.1g fixed the issue, antiskate adjusted using the LP is at 1.7.

Chakster (and others) you mentioned 3g VTF with brush, if 2.1g with brush sounds good should I still go all the way to 3g? or keeping it lower as long as it tracks is desirable? I suspect that good tracking at 2.1 with the Hifi news LP doesn't mean it will always track that well with other LPs, is that accurate?
Yesterday I listened to vinyl for the 1st time in 38 years for 8 or more hours .... a mix of LPs from initial pressings to modern ones, even modern LP's highly praised by guys like Fremer (which I respect very much) although dead silent in terms of noise the dynamics and mastering in general were not comparable to others, the Wildflowers Tom Petty album was an example, I expected more from it. A Journey - Escape 1981 original Columbia pressing sounded incredible. I am very very excited rediscovering vinyl, I can say now that all my efforts and money throw at it were worth it.
Thank you all for your help, I am grateful to know you here online.
