R50 BLOOM 3

Specially rigid black aluminum cantilever

Normally the sound of aluminum is very natural, but cannot extend to high frequencies perfectly. In order to achieve both its characteristic natural sound and the wide range reproduction, the R50 Bloom 3 has a newly developed rigid aluminum cantilever.

Cartridge Body For REAL STEREO

The Non metallic body has two kinds of hard material to prevent external disturbances from influencing the generator system and also it prevents eddy currents inside the case from effecting the generator output signal and resonances occurring on the body surfaces. 

Stylus

The stylus used in the R50 Bloom 3 is the line-contact stylus which can playback up to 40 kHz. And also it has the edges of the diamond shank set parallel to the sides of the cantilever. Using this type of stylus, the hardest axis of the crystal is aligned to act as the contact point with the record groove. This gives stable and smooth tracing and produces a very refined sound, with the additional benefit of giving the stylus an extended life.

Super High speed reproduction engine

This circuit is specially designed to null magnetic resistance within the magnetic gap, and enables high speed power generation of signals over the entire bandwidth without time delay.  This circuit can also instantly and perfectly eliminate any remaining eddy currents.
