Description

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.

 

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 LED’s.

 

Low Impedance concept, aided by the thick wires for ground connection, is critical for componentry adopting the badge of premium Hi-Fi. This design concept begins in Yamaha’s premium Hi-Fi components with the A-S1200, helping to present an open, natural sound stage, bringing the artist and listener closer together.

 

Cut directly from pure brass, the luxurious speaker terminals comfortably fit the human hand for effortless tightening, achieving a highly secure connection.

 

Warranting the ‘Premium Hi-Fi’ badge, the A-S1200 adopts a Mechanical Ground Concept, inherited from both the A-S2200 and A-S3200. The concept begins with the bolts of the feet welded directly to the main chassis, followed with the large heat sink, power transformer and block capacitors also directly bolted to the chassis. Through this design, unwanted vibration is avoided, achieving expressive and rhythmic bass, presenting the ‘Groove’ of the music to the listener.

 

Completing the rigidity of the amplifier are the heavy-duty silver-plated metal feet.
