Incorporating the main design philosophies of the S2100 series with some minor changes, the S1100 series completes Yamaha's premium hi-fi offering. With the same retro design as the S2100 series including the wooden side panels, and similar audio results, this range will again suit the audio enthusiast. Also ideally matched with a pair of Yamaha's Soavo range of speakers.

The basic design of the power amplifier circuit adopts Yamaha's own, uniquely developed Floating and Balanced Power Amplifier technology. Adopting output elements with the same polarity on the plus and minus sides of the output stage, and also completely separating the NFB (Negative Feedback) circuit and power supply into total of four plus and minus sides of the left and right channels, results in thoroughly symmetric push-pull operation of the output stage, Completely floating the entire power amplifier circuit from the ground removes any negative impact of minute voltage fluctuations or ground noise. Moreover, the output elements are comprised of MOSFETs, which provide a warm and natural sonic character. The use of MOSFETs, which have the same polarity on the plus and minus sides, further evolves the ideal of a complete symmetrical design, to eliminate sound quality variations due to difference in polaritya major distinguishing characteristic of the Floating and Balanced Power Amplifierresulting in sound with a superior signal-tonoise ratio and superbly well-defined sound field.
