Yes, Nutella, I remember that table. Very good setup for the money. There is without a doubt a very special synergy with the Vector and Basis tables. If it were me, I'd sell the table with the Vector since both are the older models. You should be able to get most, if not all, of your money back. You might do better selling the two separately, but that's really hard to know.
Anyway, I completely agree with Doug if you are looking for a better arm. Both the Tri-Planar and Schroeder would be in the top tier. Then again, I've not spent time with a Model 3 and there are some very good reports about the Graham Phantom.
There is not much detail I can share about the Vector dampening fluid level. I think it's best to start with just enough in the bath so that the bottom of the housing just begins to contact the oil. Then listen and add a bit at a time until you think the bass is tight and the dynamics are still there. You'll probably end up a millimeter or so below that small horizontal bearing.
Nutella can probably share how bad the Vector sounds with no dampening at all since I neglected to send him the oil the first time. :) Definitely don't want to hear it that way as I recall.
