AVIDHIFI Reference Ruby

As a low-output moving coil cartridge with a 0.32mV output, it requires a high-quality phono stage capable of handling MC cartridges. You should ensure your preamp or phono stage supports a load impedance greater than 100Ω to get the best performance.

The solid ruby cantilever is exceptionally rigid and lightweight, which allows the stylus to track the record groove with extreme precision. This results in superior resolution, faster transient response, and a more open, detailed soundstage compared to standard aluminum cantilevers.

The Micro-Ridge profile is highly precise and requires accurate alignment to extract maximum detail from your records. We recommend using a high-quality protractor and tracking force gauge to ensure the 2.0g tracking force is set correctly for optimal performance and record longevity.

With a net weight of 9.1g, the Reference Ruby is compatible with most modern high-end tonearms. However, you should verify that your tonearm's counterweight can balance a cartridge of this mass and that your arm's effective mass is suitable for the cartridge's compliance.

Like most high-end moving coil cartridges, the suspension and internal components will settle after some initial use. You can expect the sound to open up and reach its full potential after approximately 30 to 50 hours of playback.

Due to the delicate nature of the Micro-Ridge stylus and ruby cantilever, use a high-quality stylus brush and move it only from back to front. Avoid using liquid cleaners unless they are specifically formulated for high-end MC cartridges to prevent damage to the suspension.
