Large capacity power supply unit delivers energetic, dynamic sound with fast response
The A-S2100 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-S2100. 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.
Symmetrical design in pursuit of ideal stereo reproduction
The left-right symmetrical construction with the power supply in the centre and the power amp blocks on the ends achieves greater separation of the left and right channels—necessary for proper two-channel stereo reproduction—and ideal weight balance. Including fine tuning by a centre frame which extends from the front to the back of the casing, the A-S2100 has superb mechanical rigidity and installation stability that dramatically lessens the impact of external vibrations on sound quality.
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 phone cartridges.
Headphone amp with fully discrete configuration
The headphone amp also is equipped with fully discrete configuration, for preeminent drivability and damping properties. Included as well is a specialised level trimmer that responds to various load impedances. The superior quality sound that only the A-S2100 can attain is yours to enjoy, even when listening on headphones.
Elegant design with luxurious real wood panels
The refined design and construction of the A-S2100 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.
Original speaker terminals combine ease of use and beauty with high sound quality
Our meticulous obsession with quality continues through to the speaker terminals, which are the last and crucial link in the audio chain. Featuring screw type terminals. with originally designed handles, these are created by cutting pure brass, enabling secure connection with no reduction in sound quality. Contoured to the shape of human fingers, they not only look beautiful, but can be turned easily and fastened tightly with minimal effort. They are also compatible with connections using banana plugs.
Remote control with simple design and superior texture
The supplied remote control features a design complementary to the aluminium panel of the amplifier itself, with a simple, easy-to-understand button layout and gorgeous metallic texture. In addition to the basic volume adjustment and input switching controls of the A-S2100, it can also be used for operation of the companion CD-S2100.
