Commentary
A belt-drive player system developed with an emphasis on basic performance.
It uses a hysteresis synchronous motor developed specifically for the turntable and is driven by a highly accurate polyurethane belt.
A 31 cm aluminum die-cast turntable is used for the turntable.
Newly developed universal type is adopted for the arm, and a lifter is mounted.
The cartridge is an IM type and the shell is international standard, so the cartridge can be replaced.
The cabinet has a walnut finish and the dust cover comes with a semi-transparent acrylic case.
The acrylic case is designed with a fleece top that stops at any position.
