This is one of my favorite cartridge and I'm very pleased with the results. This cartridge is part of clearaudio's next generation cartridges.
Here's the manufacturer's specifications:
The new Clearaudio Moving Coil Generation with up to 100dB dynamic range! Clearaudio significantly improves their fully symmetrical MC design, first patented by Clearaudio in 1980. The Generator has been redesigned in a revolutionary way of positioning and doubling the magnets to 8 pcs. so the coils are operating in a much stronger magnetic field using the strongest magnetic material available at this moment: Super Neodymium. Through these achievements, the efficiency has been raised by 30%, which results in an output of up to 0.9 mV at 5cm/sec.
A new Micro-HD-Diamond tip, providing a hybrid parabolic geometry with the following stylus radii (0.008mm x 0.040mm) is now used. The total mass (0.00016g) is a fifth of the previous diamond stylus. Cartridge body resonances, while tracking in the groove, are minimized through a twelve-finger design of the mounting plate, with different radii on the cartridge body, which is a result of our constant research and sophisticated development.
The Concerto is made out of Satinee Wood. The generator construction is mechanically, magnetically and electrically absolutely symmetrical - Clearaudio's unique design is like no other! The moving coils use Clearaudio's proven 24 ct. pure gold coils.
The New Dynamic Series of Moving Coil cartridges featuring multi-finger resonance control body design, low mass coils and Micro HD Stylus! The Clearaudio Concerto features a Satinee-Wood Body, Symmetrical 24 Ct gold wire coil, 50ohm internal impedance, medium compliance, solid Boron cantilever and an output measured at 5cm/sec!
