About This Product

Taking advantage of the many years of experience of our partner transformer manufacturers, we have adopted a large toroidal transformer with an original design for the power transformer. We pursued a high signal-to-noise ratio by reducing the vibration of the transformer to the utmost.

■Features

- Equipped with a common mode noise canceling circuit that prevents noise from entering the power supply circuit and a large-capacity smoothing capacitor that reduces the impedance of the power supply, achieving a wide frequency response and sound quality with a low center of gravity. We paid particular attention to the materials used, including the transformer and other parts that affect sound quality, including non-magnetic metals. - Adopts a low current and voltage amplification circuit, including differential input and driver circuit, and reflects the idea of ​​emphasizing S/N ratio in the circuit design. - Minimize the amount of NF to pursue a lively sound that emphasizes the bare characteristics of the ball. - Adopts a completely separated left and right layout from input to output. Achieves more three-dimensional localization by pursuing channel separation. - Output stage KT-88, KT-100, 6,550, and EL34 can be selected without changing circuit constants. By customizing it according to the listener's sound preferences, you can pursue your own unique sound. -The exterior uses gold-plated brass material and top-quality side wood that gives warmth. We have realized not only the sound, but also the joy of seeing and holding it.
