The interior has been completely refreshed! The main part of the SQ38F is an independent power amplifier, the famous MQ60. The natural, gentle sound quality with a high sense of transparency is attractive. You can relax and enjoy classical music and vocals in a natural way. The deep sound quality that cannot be expressed with the latest vacuum tube amplifiers is exceptional. The exterior has stains, corrosion, paint peeling, etc. (Mizusaki Ryo)
