cylindrical aluminum cantilever.

cartidges are made of wood, a natural and unique material for
acoustic products. Wood is an excellent material for a cartridge, but
difficult to use. So when we were informed from Japan about a new
moulding material based on 55% grinded wood in a resin matrix, that
was to be processed by injection moulding just like thermoplastic
material, the chance of making even more complicated structures in
the design became of high interest.
well-known Japanese tradition in decorative art and lacquering
techniques also became of interest for the presentation of a quite
new look for the Rondo models. Rondo Series comprises Rondo Red,
Rondo Blue and Rondo Bronze models. The chosen surface colours and
decorations are basic Bronze - Blue and Red lacquer modulated by
black shadows. We decided that the tooling process was to take place
in Japan based on the drawings and specifications made by Ortofon
integrated Ortofon MC-system used for Rondo models involves new and
well-known components responsible for the exclusive Ortofon sound
quality and easy mounting:
use of Neodymium magnets are implemented for achieving 500µVolt
high outputs - to obtain the best signal to noise ratio for the
combination of diamonds and cantilevers with individually developed
damping systems for the models was arranged for very linear
frequency response and a high tracking ability.
very special genuine copper wire with a two-layer gold plating was
chosen for the armature windings. The material Aucurum shows
excellent resistance to corrosive elements from the environment and
thereby stabilises the conductivity of the small number of armature
windings in the system, which - again - is very important for the
quality of sound.
very close mechanical contact between the wood-based housing and
motor units has resulted in a new homogeneous sound quality. By
using wood we have learned about the amazing non-resonant influence
wood makes on the sound image.

snappy and sophisticated cartridge......the treble is very fine and
avoids tizziness...the bass is remarkably articulate and
muscular...it reaches that bit further into the sound to pick out
fine details in both the voices and instruments...It's a strong
get what you pay for. With detail, power and resolution above the
assembled competition, the Red makes a good case for its price"
