How old is your stereo amplifier? Maybe it’s time to sell the “old horse”, and instead get a “purebred” more modern analogue - the Yamaha A-S1100. In the next Yamaha A-S1100 review, we will talk about the pros and cons of the selected model, summarize the available Yamaha A-S1100 specs.
This device, which is a one-stroke amplifier of a special design, provides excellent amplification of both half-waves of an analog audio signal from sources of all types (CD players, digital-to-analog converters, etc.) due to careful fine-tuning for optimal sound quality. Fully realizing the possibilities of single-cycle amplification, the A-S1100 clearly reveals the internal potential of the used audio components, including those made by other manufacturers. It delivers 90W at 8-ohm load.
This amplifier uses a fully discrete configuration of all stages of sound reinforcement using only carefully selected high-precision components from input to output. The slew rate of the audio signal has been increased to provide a faster and more powerful response to high musical notes. In addition, tone control circuits can be turned off to activate a fully discrete configuration that bypasses the integrated circuit of an operational amplifier by simply setting the bass and treble tone controls to their center positions. Due to the increased throughput of the high-current line and the use of 100% low-impedance circuits, including wire connections of the main ground points with screw terminals, the A-S1100 extremely efficiently drives loudspeakers acoustic systems.
On the board there is a implemented compact circuit for connecting vinyl players. Due to this, you can connect players with both a moving coil (MC) and a moving magnet (MM). The rest is displayed on the back side. By the way, terminals deserve special attention. Like the amplification units themselves, the connectors are clearly separated by a central array of inputs. Through these very central “inputs” you can connect both the mentioned record player and a set of standard products.
