Brinkmann's 9.6 tonearm ($3990) resembles the German company's longer, more expensive 10.5 and 12.1 arms, which in turn resemble the legendary Breuer. The new arm includes the same headshell, armtube, mounting socket, and cueing device used in the other arms. The bearing system differs, though the Swiss-made ball bearings are identical.
While the more expensive arms use traditional fixed-gimbal bearings, the 9.6 has a unipivot-like construction for the horizontal bearing. The weighted arm housing sits on a small ball that rests on a pivot, also as in a typical unipivot design. A second ball at the bottom of the housing prevents "arm lean," but since the arm's weight rests on the top ball, the lower one isn't critical, and I could feel some play when I handled the arm. Vertical arm motion is effected via a second pair of captured bearings. This arrangement allowed the use of less costly parts and kept the price down, Brinkmann says. The arm's effective length is 248mm (231.5 from pivot to spindle, plus 16.5mm of overhang), while its effective mass, referenced to the center position of the headshell slot, is 12gm.
