Sansui - AU-3900 Solid state integrated amplifier

The Sansui AU 3900 is a high-end integrated amplifier. This model shares the same low-distortion circuit design as its larger predecessor, the AU-4900, but with slightly lower power. The unit features a sleek, matte-black front panel and solid aluminum knobs with tactile click positions. In terms of sound, the AU 3900 delivers the renowned, natural and beautifully balanced Sansui sound: deep, controlled bass, a very transparent midrange, and silky-smooth highs.

Specifications:
• Total Harmonic Distortion (THD): < 0.15% at rated output
• Frequency Response: 10 Hz – 40,000 Hz

The Sansui works perfectly.
