Ruby Z upgrades this famous model to full “S Class” status. It features the new Zebra wood body, second only to Ebony for its resonance characteristics, offering bass weight and pitch definition, midrange linearity and high frequency clarity with a natural musicality. The new Micro Ridge stylus is featured, providing enhanced tracking, resolution and groove integrity. The generator is based on the Ruby square plate and output is .35mV. The Ruby Z low output is best used with phono stages offering greater than 60dB gain, loaded at 400 ohms or higher. The Ruby Zebra cartridge weighs only 10.6 grams, making it ideal for a wide range of tonearms, including today’s state-of-the-art, and vintage models lacking the energy control, bearing designs, or counter-weight range.
