The Sansui AU-607 is a high-performance integrated amplifier equipped with tone controls and a subsonic filter. A notable feature of this amplifier is its excellent mid-range sound output, making it a masterpiece that vividly expresses the sound pressure of operas, guitars, basses, string instruments, and even the cheers of a stadium, creating a sense of realism. I was fortunate enough to acquire a Sansui 907F, so I would like to offer this to someone who appreciates music with a focus on sound quality. - Brand: Sansui - Model: AU-607 - Features: Tone Control - Features: Subsonic Filter - Features: Mute Function - Controls: Volume Knob - Controls: Bass Adjustment Knob - Controls: Treble Adjustment Knob The exterior is also quite clean, and it produces a very good sound.
