Sumiko Blackbird Moving Coil Cartridge - One of Uncle Kevvy's faves!
Designed for exceedingly low noise levels, wide dynamic range and the highest possilbe fidelity in its price class; destined to become an analog classic. Each cartridge is assembled using time honored, labor intensive techniques, hand calibrated and critically auditioned to meet the most rigorous standards of consistancy.
The main advantage of high output moving coil cartridges is the elimination of any additional gain stages, resulting in an overall reduction of the noise floor. With 2.5mV directly driving a standard 47k Ohm RIAA phono stage, the best possible signal to noise ratio is realized. Nothing but music emerges from your most treasured recordings. The "open generator" body design was chosen to prevent the build up of external resonances that create distortions common to typical "enclosed body" phono cartridge designs. Additionally, an inertia block, connected to the generator housing, greatly reduces internal resonances as well. A special hand-ground elliptical stylus is fitted to a Long Grain Boron cantilever chosen for its rigidity and low mass characteristics. This combination provides a most efficient energy transfer from stylus to coil resulting in superior tracking and greatly extended low bass response. Synthetic rubber was employed for the cantilever suspension to provide superior dynamic range and consistent tractability for years to come.
