Integrated amplifier with slim design.

The phono circuit is divided into three stages and uses low-noise transistor, IC and active / passive technology.
It is also compatible with MC cartridges by switching the internal switch.

High-purity sound quality is achieved by the design of the circuit without tone control, etc.

A large toroidal transformer is used for the power supply section.
