The Yamaha A-S201 integrated amplifier is an affordable, modern model that will meet the needs of many music lovers. The device is made in a solid case with a strict front panel, the placement of controls on which is well thought out. The user-friendly display provides a convenient indication of the selected input and the main operating modes. The device is equipped with a remote control.
The Yamaha A-S701 integrated amplifier differs from its analogues by increased workloads on its components and the introduction of high-end sound circuits. The elegant metal construction, which has high anti-resonance properties, is able to protect the internal elements from damage. The model is characterized by the ability to connect digital devices, due to the presence of optical and coaxial connectors.
The Yamaha AS 2200 uses fully balanced circuitry and uses the highest-end components. There is also balanced switching, as well as a built-in phono corrector for both movable magnet (MM) and movable coil (MC) heads. Developing up to 160 Watts in each channel when operating on a load with a nominal resistance of 4 ohms, the amplifier demonstrates a damping coefficient exceeding 250.
The output power of the Yamaha A-S3200 is 100 Watts per channel for an 8 ohm load, the dumping factor is 250 units, and the device weighs 24.7 kilograms. The model also has a built-in phono corrector for MM and MS heads.
