With unmatched experience in every facet of music creation, embedded deep in the Yamaha DNA is an intimate understanding of the emotional essence of music and music creation. Conveying the artists' emotion through our Hi-Fi equipment is a fundamental component of the Yamaha design philosophy. >Toroidal Transformer Usually reserved for flagship Hi-Fi components, the A-S1200 benefits from the technical proficiency and absolute musicality of a toroidal transformer. Combined with an array of high-end Hi-Fi features and components, the toroidal transformer assists in ensuring the musical emotion is conveyed to the listener. Gorgeous Level Meters The level meters are both a nod to the nostalgic era of Hi-Fi, while simultaneously demonstrating the return of pure Hi-Fi for today's discerning enthusiast. Visually presenting the dynamics and pulse of the music, the level meters imbue a warm feeling through their softly illuminated LEDs. Openness An open sound stage presents the listener with a musical experience that is similar to being at the live performance. True Hi-Fi delivers this openness in the sound, transforming the listeners' musical experience, bringing them closer to the artist. Thick Wires for Ground Connection Our low Impedance concept, aided by the thick wires for ground connection, is critical for componentry adopting the badge of premium Hi-Fi. This Yamaha design concept begins in our premium Hi-Fi components with the A-S1200, helping to present an open, natural sound stage, bringing the artist and listener closer together.

Through this design, unwanted vibration is avoided, achieving expressive and rhythmic bass, presenting the 'Groove' of the music to the listener. Chrome-Plated Iron Feet Completing the rigidity of the amplifier are the heavy-duty chrome-plated iron feet.
