AVIDHIFI Reference Ruby Cartridge
Available to Order
Solid Ruby Cantilever
The Reference Ruby takes its name from its cantilever material. In order to maintain a low moving mass, the long ruby cantilever carries fewer coil turns, and thus has a lower internal resistance and output.
Micro-Ridge Diamond Stylus
The Reference Ruby is fitted with a micro-ridge diamond stylus — a solid diamond, not bonded. The micro-ridge stylus is well polished and precisely mounted on its ruby cantilever.
Solid Aluminium Body — Five-Axis CNC Machined
The magnets are neodymium and the coils are specially-treated 99%-pure copper. The yokes are CNC laser-cut from mild steel, then gold-plated. The flat front and parallel sides of the body make alignment straightforward. The construction is precise and purposeful — not the deliberately artisan aesthetic of some high-end MC cartridges, but the flawlessness of a perfectly-proportioned machined component.

Who Is It For?
The Reference Ruby is for the serious vinyl enthusiast who has assembled a premium front end and wants a cartridge to match. Its compliance is low at 9cu and, combined with the 9.1g body weight, renders it very compatible with today's higher effective mass tonearms in the 11–16g range. Those building a complete AVID front end should consider the AVIDHIFI Nexus Tonearm as the natural partner, and the AVIDHIFI Acutus Reference Chrome as the turntable platform on which the Reference Ruby is designed to perform at its best. Those exploring the wider AVID cartridge range should also look at the AVIDHIFI Boron MC and the AVIDHIFI Ionic MC Cartridge below it.
