The first part of the tonearm to handle modulations from the record groove and cartridge, is the moving part of the tonearm. Head shell, armtube, sliding pipe and counter weight, has to be well considered and well assembled, to avoid any resonances to disturb the delicate signal.
The head shell is a very stiff construction, machined of one solid piece of aluminium, glued by 2-component epoxy onto the seamless carbon fiber armtube, which is a double carbon fiber tube construction with damping in between, to avoid coloration to the sound. The armtube is fixed in a groove, on top of the sliding pipe, which is machined of 2 pieces of solid aluminium and glued by 2-component epoxy.
The space between the airpipe and the sliding pipe, is 50 micron, as we found this as the most userfriendly.
The azimuth adjustment is very well considered – a slot on the bottom side of the head shell, where an “azimuth-plate” perfectly fit = 100% contact, the azimuth is simply adjusted by tighten or untighten the 2 screws holding the cartridge, and then twist the cartridge to a perfect azimuth. At Bergmann Audio, we don’t believe in a twistable head shell in the armtube, as this solution never will be as strong and stiff, as the construction we have made on the Odin tonearm.
The tonearm wire is made in one piece from the cartridge clips to the DIN connector, to secure as pure signal transmission as possible.
- Headshell machined in solid aluminium. The design ensure optimal stiffness.
- Azimuth plate. 100% contact to the headshell and cartridge.
- Armtube is a double seamless carbon design, with damping in between.
- Sliding pipe floats completely frictionsless on the airpipe.
- Tonearm wire in one piece from cartridge clips to the DIN connector.
- Counter weight, decoupled from the armtube by 3 rubber strings.
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 do 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 filter, which prevents dust particles in entering the system. The filter is replaceable when necessary.
- Airpipe supported in both ends, for optimum stiffness.
- Base plate. Can be moved forth and back, to obtain perfect overhang and for perfect leveling of the
airpipe. - VTA plate- where all functional parts are fixed.
- VTA adjustment screw.
- VTA pillars fixed to the base plate. VTA plate can be adjusted on the pillars by turning the VTA adjustment screws.
- Screws to tighten the VTA plate, when VTA is adjusted.
- Air input, to support the floating part with an extremely frictionless air cusion.
- Air flow can easely be adjusted by a valve at the airsupply.
- DIN connector, to fit all brands of phono cables.
