bukanona, to be polite the DV507 is a nightmare.
mglik, it is always best to start out with a lighter arm. You can always add mass, hard to take it away.
chakster, I love Reed arms. The 2G is a better design than the 3P. Both use the same tonearm wands of varying masses. The 2g is a neutral balance arm while the 3P is not. The 2G's vertical bearings are two points in the plane of the record (and stylus) with the counterbalance also in the same plane, just like the Kuzma 4 Point. Once you have the tonearm in neutral balance it will stay in whatever vertical position you put it in while the 3P will swing up and down around the balance point like a scale. This is called static balance. For a tonearm neutral balance is always better. The Schroder CB and Triplanar are also examples of neutral balance arms. Interestingly, the Schroder LT is a static balance arm. I think Frank was stuck with this because of the arm's geometry and the swinging bearing platform did not give him room to lower the vertical bearing to the plane of the record. Still an incredible arm.
