Thor was the most popular of all Gods. Thor was worshipped by most – he was the God of people. He made lightning and thunder as he drove over the clouds in his chariot drawn by goats swinging with his hammer, Mjølner. Thor stood for physical strength.

Thor`s role was, to maintain law and order.

Design – Thor Tonearm
In the design and construction of Thor, we stay to our idea of simplicity: As few parts and assembling as possible, to avoid resonances.

The carbon fibre arm tube is traditional for Bergmann tonearms- well-considered construction in few parts, made as a double tube construction, with damping in between the tubes, to avoid any colouration in the signal path, generated by the stylus tip and the record groove. Even the most powerful musical passages in the music will be reproduced with musical ease and very low distortion.

The tonearm wire is- as usual in Bergmann tonearms- in one piece from cartridge clips to the DIN connector. The DIN connector ensures user flexibility for connection of the preferred interconnects phono cable.

The counterweight is decoupled from the arm- again to avoid any resonances.

Strength in the linear tracking air bearing tonearm

The Linear tracking tonearm tracks the record as it is pressed = no tracking error.

The benefit is a distortion-free and relaxed reproduction, even at complex passages.

One more important advantage of the air bearing is the tonearm’s immunity to acoustic feedback, as the floating part (arm tube and headshell) has no mechanical contact to the fixed part of the tonearm and the turntable. The only contact is through the stylus tip and the tonearm wire.

Timbre, details and nuances, is a natural part of the transparent and vivid acoustic image.
The 3D spaciousness, layering between instruments and zero tracking error is something traditional tonearm finds hard to achieve.

Floating part – perhaps the most important part, of an air bearing tonearm!

The first part of the tonearm to handle modulations from the record groove and cartridge is the floating part of the tonearm (arm tube and headshell). Headshell, arm tube, floating pipe and counterweight, have to be well considered and well assembled, to avoid any resonances to disturb the delicate signal.
The headshell is machined of one solid piece of aluminium, glued by 2-component epoxy onto the seamless carbon-fibre arm tube, which is a double carbon fibre tube construction with damping in between, to avoid colouration to the sound. The arm tube is fixed in a groove, on top of the floating pipe, which is machined of 2 pieces of solid aluminium and glued by 2-component epoxy.

At Bergmann Audio, we don’t believe in a twistable headshell in the arm tube, as this solution never will be as strong and stiff, as the construction we have made on the Thor tonearm. Azimuth is adjusted by adding a spacer between the bottom of the headshell and cartridge body. By tightening and untightening the 2 screws holding the cartridge, the cartridge can hereby be twisted to achieve a perfect azimuth.

The tonearm wire is made in one piece from the cartridge clips to the DIN connector, to secure as pure signal transmission as possible.

Armtube is a double carbon fibre construction, with internal damping.
The floating part floats completely frictionless on the airpipe.

Air supply

The air supply has been the object of our greatest attention. The goal is to design a silent air supply, which could be placed in the listening room, and deliver an even, clean and dry air flow.
The pump is an oil-free, long-life unit, which does not require much maintenance.
The impulses from the pump are absorbed in an encapsulated reservoir. This results in an even airflow to the air bearing. The air supply is mounted with a dust filter, which prevents dust particles in entering the system. The dust filter is replaceable when necessary.
