Schröder: Completely Unbiased
A pivoted straight-line-tracking tonearm? The description is far less oxymoronic than it seems, given the arrival of the Schröder LT tonearm ($8900). This fascinating and apparently very well-executed design works by augmenting the main arm pivot with an extra pivot at the base, the latter said to offer exceptionally low resistance to the arm and cartridge as they follow the inward spiral of the groove. The geometric relationship between the two pivots is such that the headshelland the cartridge and stylusmaintain perfect tangency to the groove from beginning to end. Thus the headshell requires no offset angle, which also means that no anti-skating force is required. Very cool.
