Maintained. MC boost transformer using an amorphous troidal core transformer. The sound quality is so smooth and amazing that you can't imagine from its size. The impedance is switched in 4 levels, including PASS, and is compatible with various cartridges. In addition to the exterior and disappearing characters, you can also see a feeling of use such as dullness, abrasions, etc. (Kobayashi Hitoshi)
