Dedicated single-ended amplifier for all types of audio sources
Since this device employs a dedicated singleended amplifier, it provides excellent response in amplification of single-ended analogue sound from all kinds of audio sources, such as CD players of D/A converters—and the A-S1100 takes advantage of this in having been carefully fine-tuned for optimum sound quality. By fully utilising single-ended amplification, the A-S1100 transparently draws out the intrinsic qualities of your favourite audio devices, including those made by other manufacturers.

Thorough low impedance design ensures powerful bass response with extremely dynamic, energetic feel
By strengthening the capacity of the high current route (raising the section area of the cable core wire to about 60% of that of the A-S1000) and by pursuing thorough low impedance design, including forming screwclamped wire connections of major ground points, the A-S1100 boasts excellent speaker drive power with a damping factor of more than 250 (8Ω, 1kHz). Along with the large-capacity power source transformer equipped with an EI core, this design delivers bass reproduction that is both strong and uplifting.

Large capacity power supply unit delivers energetic, dynamic sound with fast response
The A-S1100 employs an original EI transformer, carefully customised for optimum compatibility with the chassis. Combining four large capacity carbon sheath block capacitors delivers an energetic sound—even during high volume—that is possible only with the A-S1100. Moreover, since the control amp and control system is equipped with twelve shunt type local regulators that prevent deterioration caused by currency fluctuation, a clean and stable power supply is achieved. The EI transformer is mounted on the chassis using brass washer, restricting internal vibration that would result in noise.

Discretely configured phono amp
The phono amp is comprised of an MC head amp and an equaliser amp, each of which are discretely configured, resulting in a rich sound with pronounced musicality, when playing vinyl records with both MC and MM phono cartridges.

Elegant design with luxurious real wood panels
The refined design and construction of the A-S1100 reflects Yamaha’s commitment to fine craftsmanship and art, uniquely drawing on its long experience as a world-class musical instrument maker. The metal front panel and the side wood panels have been beautifully integrated by the masterful use of advanced processing technology. Moreover, the dials and tone controls are machined aluminium knobs, for a richly textured finish and graceful touch.
