Yamaha A-S2100 integrated amplifier is a high-grade hi-fi amp and the most popular seller of Yamaha's high end models. with advanced circuitry and signal loss elimination for truly emotional and dynamic natural sound.
Yamaha’s unique ‘Floating and Balanced’ power amp circuit design aligns elements of same polarity in the output stage. The negative feedback circuit and power supply is completely separated into four +/- sides of the left and right channels, essential for accurate two-channel stereo reproduction, resulting in a thoroughly symmetric push-pull operation.
MOSFETs also provide a warm and natural sonic character, eliminating deviations in sound quality caused by different polarities, a major distinguishing characteristic. Combined with mechanical rigidity, floating the entire power amp circuit reduces any negative impact from minute voltage fluctuations or ground noise. Overall this creates a superior SN ratio and well-defined sound field.
Thoroughly splitting tone control circuit from the signal system achieves a fully discrete assembly; enhancing response and slew-rate for better vitality, detail and smoothness in the high range. Signal loss is greatly reduced via screw clamps, thick cables and by connecting the power step to speaker terminals. An improved damping factor/power and driver capacity create a vibrant and powerful bass reproduction.
Large Capacity PSU
An original EI transformer, customised for optimum compatibility, is built into the chassis. Combining four large carbon sheath block capacitors delivers energetic sound even at high volumes. Equipped with twelve shunt type local regulators, the control amp and system prevent deterioration caused by exchange fluctuation producing a clean and stable power supply. The EI transformer is mounted on the chassis using brass washer restricting noise-causing internal vibrations.
The phono amp comprises MC headphone/equaliser amp, each discretely configured, resulting in rich sound with pronounced musicality when playing vinyl records with MC or MM phono cartridges. The headphone amp’s fully discrete configuration affords it preeminent drivability and damping properties. A specialised level trimmer responds to various load impedances. The superior quality attained by only the A-S2100 is yours to enjoy even when listening on headphones.
Screw type terminals with originally designed handles, created by cutting pure brass, enable a secure connection with no reduction in sound quality. Contoured to fit your fingers, they are easily turned and tightly fastened with minimal effort. Also compatible with banana plug connections. The insulators adopt Yamaha’s original metal legs for best vibration control. Select point installation via supplied spikes, plane insulation via supplied pads or use combined with an interlocking rack.
Level metres offer visual music enjoyment through the rapid and delicate movement of needles. LED illuminated softly from inside gives a warm and beautiful lamplight feel. The metre indicators and VU display can be switched to peak display according to preference. The window is precision-fit to the panel, completely flat with no gaps for an elegantly seamless appearance.
The polished design assures fine craftsmanship honed over years of creating world-class instruments. The metal front and wood side panels are masterfully integrated via advanced processing while machined aluminium dials and tone controls give a richly textured finish and graceful touch.
The high-quality digital volume control comprising of only ladder-type resistance, prevents slew-rate decline or sound colouring. There is an exceptional fast response to large volume changes and steep transients. Triple-parallel method is much less detrimental to sound than straight-line tone controls.
