Yamaha A-S1100 review
The model has a discrete circuit topology using selected premium components, it has a high slew rate and has spaced power amplification stage boards, which ensures complete separation of channels and eliminates their mutual influence on each other. Between the boards there is a power supply unit equipped with a massive transformer with a W-shaped core, which is mounted on the chassis using brass spacers in order to minimize vibration and noise. The PSU uses four high-capacity capacitors in carbon shells. Comparing Yamaha A-S1100 vs Marantz PM8006 we can see that Yamaha has power output of 90/8 while Marantz produces 70/8 W/Ohm. 
Marantz PM8006 review
The Marantz PM8006 is equipped with an upscale built-in phono equalizer, the circuit of which has been completely redesigned by the company's engineers to exactly match today's current requirements for vinyl reproduction. The amplifier also uses proprietary HDAM modules that have proven themselves in the Marantz technique. The Marantz PM8006 has a distinctive signature sound with smooth mid frequencies, focused and deep bass and beautiful, airy highs. 
Yamaha A-S1100 pros & cons
Pros
- Control knobs and switches operate very smooth with a solid feel
- The connectors are clearly separated by a central array of inputs
Cons
- I wish the volume knob had a tiny LED which would indicate volume level
Marantz PM8006 pros & cons
Pros
- It retains some of Marantz's signature homeliness, but to a lesser extent than previous amplifiers.
- The choice of input is huge, which allows you to connect almost everything imaginable
- Very high-quality input selector with distinctive latches
Cons
- Not enough dynamics and bass control
