Hi-Fi Choice June 2008, Reviewed by Jason Kennedy

Ortofon MC Rondo Red is a very homogeneous all round cartridge

The Rondo Red has a very fine polished elliptical diamond and is mounted on a cylindrical aluminum cantilever. The cartridge is clearly out of the same family of sound as Bronze and Blue – all of them taking benefit from the wooden housings. Recommended load around 100 Ohm or even higher if added “air“ might be preferred.

The MC Rondo Red sound image will tend to less dynamic strength and smoother reproduction - working perfect with all sorts of not very complex music.

Ortofon MC Rondo Series phono cartridges

Rondo 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. The 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 colors 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 engineers. The integrated Ortofon MC-system used for Rondo models involves new and well-known components responsible for the exclusive Ortofon sound quality and easy mounting:
