We all know that the small things matter in hi-fi. Especially at the front end of the audio system – eg. the pickup cartridge and tonearm.
The Trans-Fi Terminator tonearm is constructed with a 6mm aluminium ‘L’ Mounting Plate. It’s machined shape and necessary slotted holes, no doubt reduce its structural and torsional rigidity.
Would there be energy loss?
The Terminator linear tracking tonearm combines an air-bearing with a (twin) ‘uni-pivot’ bearing.
Uni-pivot bearings need to be stabilised in order to handle the energy generated by a pick-up cartridge.
In this case, twin pivot points were in metal-to-metal contact with the arm-slider ‘V-brackets’ and some instability or ‘bearing rattle’ can be audible at times. Continue reading
This is a follow-up to my Terminator linear tracking tonearm post in last Feb.
I mentioned Effective Mass and how it differs significantly in the horizontal and vertical planes.
Poul Ladegaard’s “Tangential Tonearm” experimental work is informative here. Continue reading
