This integrated amplifier pursues pure sound quality while also focusing on operability, achieved through the use of a large toroidal transformer and a new SLDC structure.

Unlike conventional transformers, the toroidal transformer has a coil wound around a donut-shaped ring core, offering superior characteristics in terms of stable current supply, leakage flux prevention, and vibration prevention.

To suppress mutual interference between each circuit, the new S.L.D.C. (Signal Level Divided Construction) structure is employed.

It is equipped with an equalizer amplifier that supports both MC/MM cartridges through switching operations.

A source direct switch is included, which, when turned on, bypasses control circuits such as Bass, Treble, Balance, and Loudness.
