Yamaha A-S1200 High-End Integrated Amplifier, Silver

Yamaha A-S1200 – purely analog High-End integrated amplifier

The A-S1200 marks the start of Yamaha's High-End amplifier class: an uncompromisingly analog integrated amplifier in classic design with illuminated level meters, wood side panels and technology inherited from the A-S2200 and A-S3200. No DAC, no streaming – just music in its purest form.

Sound & amplification

2× 90 W into 8 ohms (0.07% THD), 2× 150 W into 4 ohms, with a high damping factor (≥ 250) for firm control over the bass. At its heart are a large 625 VA toroidal transformer and the "Floating Balanced" output stage topology, in which both signal halves work symmetrically with matched MOSFETs. The "Mechanical Ground" concept couples the transformer, heatsink and capacitors directly to the chassis, keeping vibration out of the sound.

Connections & controls

MM/MC phono input for high-quality turntables, several line RCA inputs (one of them as a Main-In feeding directly into the output stage), a Pre-Out and two pairs of brass speaker terminals (A/B, bi-wire capable). The illuminated level meters can be switched between VU and power display and dimmed. Headphone output on the front.

Straight talk – what you should know

The A-S1200 is deliberately analog: no DAC, no streaming, no network function. Importantly – unlike the larger A-S2200, the A-S1200 has no balanced XLR inputs; all inputs are unbalanced (RCA). The "Floating Balanced" circuitry concerns the output stage, not the inputs. If you want to make full use of a balanced source (e.g. a DAC with XLR), you should go for the A-S2200 instead.
