Yamaha A-S1100 vs Marantz PM8005

Yamaha A-S1100 review

The completely symmetric amplifier circuit includes a powerful power transformer with four large capacitors in the power supply. In the output stages, powerful MOS transistors are used. All this is based on Yamaha Floating technology, a symmetrical amplification circuit ensures that the signal circuits are separated from the chassis to avoid signal distortion caused by voltage fluctuations. On the rear panel of the A-S1100 are four pairs of gold-plated screw terminals, 3 analog RCA inputs, an input for a MM / MC pickup, a line input, recording input / output, 2 pre-outs for connecting a subwoofer, they can be used together with a second amplifier for a pair of front speakers or as headphone output. It delivers 105W (8 ohms). Yamaha A-S1100

Marantz PM8005 review

The amplifier develops the power of 35W (with an 8-ohm load), and has a symmetrical design that provides good separation of stereo channels. A custom toroidal transformer is installed in the Marantz PM8005 power supply, providing enough energy to provide dynamic sound. To eliminate electromagnetic interference, which can negatively affect the quality of audio circuits, the transformer is placed in a double screen. The source rectifier is built on high-speed Schottky diodes, and components of the audiophile class are installed in the sound circuit of the device. Marantz PM8005

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 PM8005 pros & cons

Pros

  • The uniqueness lies in the work with current feedback, which allows you to generate a large supply of energy
  • In order to eliminate unnecessary vibrations, the manufacturer created a special three-layer system

Cons

  • As for me, it is too heavy
