Specially rigid black aluminum cantilever
Normally the sound of aluminum is very natural, but cannot follow to high frequency 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 for the first time.
Cartridge Case For REAL STEREO
Item 11,12 and 13 of the vital design points make very complex demand of the body's electrical properties. Non metallic body is necessary in order to achieve these properties, and to prevent external disturbances from influencing the generator system and also, it prevents eddy currents in the case from effecting the generator output signal.
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 (magnetic circuit)
This circuit is specially processed to null magnetic resistance within magnetic gap, and enables high speed power generation against signals over entire bandwidth straightly without time delay.
