A stereo integrated amplifier from Yamaha with a toroidal power transformer, illuminated level meters and a Mechanical Ground Concept chassis. Yamaha rates it at 90 W + 90 W into 8 ohms and 150 W + 150 W into 4 ohms (20 Hz-20 kHz, 0.07% THD).
Yamaha describes the A-S1200 as pairing nostalgic Hi-Fi design with today's technology, built around three ideas: emotion, openness and groove. It is available in black or silver.
Why you will love it
Toroidal transformer and level meters
A 625VA toroidal power transformer feeds the amplifier, according to Yamaha's specification.
Yamaha says the level meters are a nod to the Hi-Fi of the past and convey the dynamics and music pulse.


Floating balanced power amplifier and low impedance design
Yamaha lists a Floating Balanced Power Amplifier among the A-S1200's main features.
Yamaha's comparison table lists internal speaker wires of super thick copper (2.0 mm).
Mechanical Ground Concept
Yamaha says the Mechanical Ground Concept maximises rigidity for expressive and rhythmic bass.
Its comparison table lists iron feet for the A-S1200.
