Analog tonearms in particular have always drawn my prime interest among all components of the audio-chain.
In the past 20+ years I have designed a good range of not-so-ordinary high-end analog front-end audio components.
Starting with the 440lbs bi-radial air-bearing and air-suspended APOLYT-turntable - continuing with the UNI-Protractor triangular alignment instrument, the UNI-P2S and the arché headshell.
However, what was always on my mind, was the all-out-assault on the analog tonearm design - actually the tonearm I always wanted for myself.
A dynamically full balanced pivot tonearm which finally takes into account all geometrical aspects, all the various inherent forces and combines all solutions in a most consequent way.
Thus the very best performance possible for any given cartridge is enabled.
This tonearm design is now accomplished.
It is manifested in the AXIOM
(ancient greek: 'that, which commends itself as evident', the premise of reasoning in logic)
Exclusive features of the AXIOM:
* VTF (vertical tracking force) non-touch-adjustment: on-the-fly - during play.
* SRA adjustment is independent from tonearm height (fixed mounting head)
* dynamic tunable effective moving mass
- from 22 gr to 42 gr effective moving mass in fixed mounting version.
- from 29 gr to 48 gr effective moving mass in SME-bayonet version.
* dynamic antiskating
- w/exchangeable inserts for any tangential curve!
* carbide hardend titanium / carbon-composite arm pipe with
internal liquid dampening on whole inner surface.
* exchangeable inserts in counterweight tuned to cartridge's compliance.
Thus eliminating low frequency resonance peak.
* the AXIOM and it’s bearing axis can be precisely leveled on it's own. This is independent from the plinth's level and done with 3 precision set screws around the center mounting screw (these are covered by the large round metal cap and not visible when mounted).
