Il semble que la firme Benz ait réussi à faire descendre quelque peu la fréquence de résonance intrinsèque du bras, de 40 à 30 Hz... ce qui reste malgré tout extrêmement élevé et surtout audible !...
La moyenne pour un bras conventionnel , tangentiel ou radial, étant entre 8 et 10 Hz .. la différence est conséquente..
De part la modif qu' ils effectuent sur le porte-cellule, ils le rigidifient et le découplent à la manière d' un Uni-pivot ..
A noter aussi que les cellules Micro-Benz sont des bobines mobiles à compliance modérées, entre 14 et 20, et que les cellules Van den Hul sont des bobines mobiles à compliance haute, entre 25 et 35 ... donc très au dessus de la grande majorité des cellules à bobines mobiles ..

Pour terminer, à la fin de l' article, je dirais qu' ils ont une façon un peu déplacée de prendre l' ensemble de la gente féminine pour une bande d' idiotes

BENZ encountered in Miami a Revox Turntable fitted with his top MC cartridge which did, however, not sound as it could have. The match was apparently not optimised.
BENZ got fascinated with this basically superb tumtable. He made the following modifications:
the built-in impedance network was eliminated and the arm was refitted with Van den Hul cables. There was still
a resonance al 40 Hz. This was not only a measured defect, but it could also be heard.
Benz hnally decided to replace the original flexible tonearm with a machined aluminium construction. This brought the mass of the arm-cartridge combination from 38 gr to 53 gr.
The base immediately improved.
But the instrument 1ocalisation was still not perfect. Benz replaced the aluminium arm to increase the mass uP front by a slightly heavier brass design which brought the total mass arm,/cartridge up to 70 gr. The sound improved further
There was still a persistant resonance at 30 Hz. It was eliminated by a new single point bearing construction. Furthermore the muting network was bridged to obtain an untampered signal path. Finally bass and instrument placement was superb.
Benz is convinced to have created a high-end tumtable incorporating the famous Revox quality, remote-controlled,
so that even the lady of the house can touch this jewel without being afraid to damage a precious record or cartridge
