I’ve been fascinated with Micha Huber’s linear-tracking pivot arms for quite awhile as they have seemed to me to be a very elegant way of addressing the tracking-error issue without having to suffer the kind of increase in horizontal moving-mass that a traditional linear-tracking arm lends to the situation. In fact, it’s precisely because of this major difference in apparent moving mass between the horizontal and vertical modes that Peter Ledermann developed a special suspension for his Hyperion cartridge, where the compliance is higher in the vertical domain than in the horizontal domain in order to account for the severe disparity in apparent moving mass between these modes.
In the case of Thales arms, this isn’t really necessary because the apparent moving mass of Micha’s arms is the same as it would be if it were a traditionally-pivoted arm. The only functional difference between a Thales arm and a more ordinary pivoted arm is in the articulation of the headshell, in order to allow the cartridge-stylus to trace the groove substantially laterally, instead of in a substantial arc. Elegant and persuasive.
Huber has now also turned his genius to the turntable itself, and mates these ideas together in the TTT Compact under review. Nothing fancy, nothing shiny … it exudes philosophical purity. But sometimes it’s in that gap between the ideals of theory and the practical applications in reality that things can sometimes unravel …
