Wilson Benesch Circle 25 Turntable and A.C.T. 25 Tone Arm
In any design, ultimate high performance can only be attained when all the
components have been optimised to work in harmony. Following this philosophy
Wilson Benesch have taken all design and manufacturing in house to create the
Circle 25 turntable. Using State of the Art Dassault CAD/CAM Systems, Wilson
Benesch precision engineer each component in the Circle 25, within a tolerance
of 0.01mm, to create a perfectly engineered masterpiece.
Forming the principle structural components of the Circle 25, the
distinctive two-part Polyoxymethylene (POM) circular plinths replace the MDF
plinths used in the original circle design. POM is a high-grade engineering
homopolymer exhibiting superior stiffness and a higher damping coefficient.
The lower plinth houses the motor assembly, which is isolated
from the upper plinth by three lossy polymer nodes. In turn, the upper plinth
sees three alloy nodes meet with unidirectional carbon fibre cantilevers to
create a unique sub-chassis suspension. The carbon fibre cantilevers are central
to the success of the Circle 25 design. They exhibit exceptional stiffness and
energy damping, providing a solid reference point for the platter and damping
any structural borne resonance. This highly optimised design translates directly
into the sonic presentation of the Circle 25, creating a wide-open soundstage,
with the ‘blackness’ and solid quality to the analogue sound.
The final element is the bearing. The Circle 25 references the
past to redefine the future. Taking elements of the original bearing design, the
new bearing combines a hardened steel shaft and captive ball bearing, with a
phosphor bronze bearing hub. With a highly polished surface finish, the bearing
ensures the lowest possible level of friction and noise, while being
phenomenally resistant to wear.
A turntable is purely a system of measurement, designed to allow
a ~10nm (0.000001mm) cantilever tip to trace a ~50µm (0.05mm) groove in a piece
of vinyl. By considering the microscopic level, it is then easy to appreciate
the beauty of the Circle 25 design. What appears a simple design is in fact a
complex and highly engineered analogue replay system.
