Ars Cyprium (latin: ore from Cyprus). This was what the Romans called copper, the first metal to be used
by mankind. Since the Stone Age, over 10,000 years ago, man has been using copper. We have taken the exceptional properties of copper, and in conjunction with our special polymer we have developed a compound platter. The musical reproduction benefits from breathtaking soundstaging and stereo depth, the representation of the instruments gains substance. The whole sound characteristic becomes clearer and more relaxed.
Platter drive is via a maintenance-free belt. The AC version of the Raven has a modified motor control.
The armboard is made from bronze as standard. Feet: three, ceramic bead blasted and silk matt black anodised aluminium, designed and built by TW-Acustic featuring ball and spring suspension.
A significant update is the provision of a new motor control unit. This is even better than its predecessor and is designed to provide support for the three-motor drive option.
Raven AC Turntable
Designed by Thomas Woschnick, the Raven AC is a true high end turntable benefiting from the finest German engineering, build quality and attention to detail. Consisting of a solid base machined from a specially developed high density polymer, a one-piece bearing and a heavy composite platter together with pure copper, this turntable ensures the ultimate in stability and control. Drive is provided by a microprocessor controlled DC motor employing quartz crystal referencing to ensure accurate speed to within 0.000000002 seconds per minute. This high torque motor enables the 10kg platter to reach operating speed within one second, via a maintenance free belt. The tonearm is fitted to the turntable via a bronze armboard. It is possible to fit up to four tonearms to the Raven at once. The result of this no-compromise approach is an effortlessly natural sound throughout the entire frequency range, extremely high resolution coupled with ultra-precise timing and a tightly controlled bass that retains all its detail.

Technical details:
Our three motors run absolutely syncronous thanks to a sophisticated motor control
The diameters of the drive pulleys are accurate to within half a hundredth of a millimetre
The drive belt thickness is ground to a tolerance of one hundredth of a millimetre
We have taken the advantages of our unique drive system to the limit and have developed a three-motor drive for the Raven One and Raven AC. We have achieved perfect syncronicity between all three motors with our new, highly developed motor control system.
The extremely precisely machined drive belt, coupled with finely toleranced and matched pulleys give the concept the optimal basis for the precision we demand. If you were of the opinion that the Raven's drive system was unique, then of course you were right! But the new three-motor drive picks up where our unique single motor drive leaves off. The Raven or Raven AC is now available as a three-motor version. Of course, any existing Raven One or Raven AC can also be upgraded.
Our new armboards make changing to another tonearm on the Raven AC easier. Where before it was necessary to replace the armboard, now it is simply a matter of exchanging the adapter insert.
