I finally read Fremer's review. Why does that guy always harp on the notion that the vertical and horizontal effective masses of a tonearm should be equal? Why should they be equal? There is some advantage in having a higher effective mass in the horizontal plane, in terms of the reproduction of low bass frequencies, most of which information is encoded in the horizontal plane. I believe it's correct to say that Frank Schroeder pointed this out on another thread here. If Fremer has reason to adhere to this belief, I wish he would explain the rationale.
