TW-Acustic Raven 10.5 tonearm.
For a long time we have received enquiries about suitable and adequate
tonearms for use with our Raven turntables. Until now, we have had to
recommend the finest arms from other manufacturers. But finally...
The first TW-Acustic tonearm will be presented (and will ship) in early
2010.
The arm was created in collaboration with the civil engineer Michael
Wiedemann Dipl. Ing, who for several years has applied himself to the
science of tonearm construction. The result is an arm that truly reflects
the same philosophy as TW-Acustic turntables: simplicity and
user-friendliness.
From the very beginning it was established that the concept would be a
straight, pivoted-type arm. The rigorously selected precision bearings are
ultra-precisely adjusted during the production process in order to eliminate
any interference in the pick-up process through stiction and the so-called
stick and slip effect. To keep effective mass to a minimum, the tonearm is
predominantly constructed from a special black-anodised aluminium alloy
which intrinsically ensures the necessary stiffness and torsional strength.
The effective mass is approximately 14g, which allows partnering with the
majority of currently available MC and MM cartridges. This universal
compatibility is further underlined by the inclusion of three different
polished stainless steel counterweights as standard, allowing any cartridge
with an operating weight of between 5g and 20g to be perfectly
counterbalanced. Of course, thanks to its 4-hole flange mount, the Raven 10.5 can easily be used with other manufacturers turntables. |
Tonearm height is adjustable with the zero-float VTA adjuster. This VTA adjuster, derived from that found on our flagship Raven Black Night turntable, allows adjustment of 10 mm
on the fly. The headshell is not detachable, but nonetheless allows for azimuth correction.
This means that any cartridge system can be adjusted in every parameter! The
integral one-piece sonically optimised copper tonearm cable (from the
cartridge tags right through to the phono plugs) does the rest ensuring
that the delicate signals arrive at your phono stage pure and
interference-free.- Magnetic Antiskate adjuster
We are confident that the TW-Acustic Raven 10.5 will contribute to a
rediscovery of your vinyl collection.
All parts are made in Germany by TW-Acustic.
