The Sansui AU-α 555 VS is an integrated stereo amplifier that was manufactured between 1989 and 1991 in Japan. This amplifier was priced at approximately ¥69,800 at its release. It boasts an effective output power of 90W per channel at 6Ω and 80W per channel at 8Ω, demonstrating a solid performance level for an integrated amplifier of its time. The unit is designed to handle low impedance loads, capable of delivering dynamic power of up to 340W at 2Ω. The amplifier offers very low total harmonic distortion (0.008% or less at 8Ω) and cross modulation distortion, indicating high audio fidelity. The frequency response is impressive, extending from DC to 100 kHz with only a ±3dB variation. In terms of input, it features two phono inputs (one for MM and one for MC) and multiple line inputs, making it versatile for various audio sources. Accompanying this functionality is a signal-to-noise ratio of 85 dB or more for MM phono, and an advanced tone control that allows for a ±8 dB adjustment in both bass and treble. The unit has dedicated video inputs and outputs, reflecting its integrated audio-visual capabilities, and ensures signal separation to minimize interference. It is equipped with a remote control for ease of use, and its build includes features to mitigate high-frequency noise impacting sound quality. Weighing in at 11.0 kg with dimensions of 430 mm in width, 160 mm in height, and 390 mm in depth, the AU-α 555 VS is well-constructed and designed for performance.
