Maintained! The main part of the SQ38F is an independent power amplifier, the famous machine MQ60. The natural, gentle sound quality with a high sense of transparency is attractive. You can enjoy classical music and vocals in a natural and relaxed manner. The deep sound quality that cannot be expressed with the latest vacuum tube amplifiers is exceptional. There is a feeling of use on the hood, such as scratches and rust. Serial 40305740 (Takasaki Atsushi)
