A step-up transformer cased by Audionics using a transformer from Partridge, a prestigious British transformer manufacturer. The natural band balance has a sense of intonation, and a pleasant tone that feels good against the skin. High 40 ohm and low 3 ohm compatibility due to cable replacement avoids sound quality deterioration due to switches, etc. There is no seal on the transformer part, and there is a thin paint crack (Kobayashi Hitoshi)
