Benz Micro Ruby-Z or ZH Cartridge
Custom order item, not avalible for online purchase.
RUBY-Z
The 4th generation of Benz Micro's Ruby series, this model has undergone years of refinement. Using Benz Micro's signature square ruby plate generator, the Ruby Z is able to extract minute textural details from the record groove due to the lightweight, non-ferrous nature of the ruby core. The Zebra wood body completes what is perhaps the most beautiful looking and sounding of Benz Micro's cartridge offerings.
