Commentary
MM type cartridge that can also handle 4 ch playback.
In addition to lowering the internal impedance of the cartridge itself, it uses a special magnet with low specific gravity and high energy product.
In addition, we have improved the orientation by using a suspension system in which the fulcrum is fixed regardless of the movement of the needle tip.
The M-7000 is designed with matrix (RM, SQ), 4 ch, discrete (CD-4) 4 ch in mind and has strict phase control.
The replacement needle V-7000/F for CD-4 uses a PM needle polished from a 0.15 square diamond block, which was specially developed to reduce the mass of the light alloy pipe cantilever and the needle tip diamond tip. This further improves the high-frequency reproduction characteristics.
