The Yamaha A-S701 stereo amplifier offers high-quality sound and powerful drive. It features innovative design technology, high-quality parts, and is created by Yamaha's rich experience and tradition in musical instrument making. Yamaha A-S701 Integrated Stereo Amplifier The Yamaha A-S701 stereo amplifier offers an extremely pure sound quality and outstanding drive power. This integrated amplifier provides a pure connection to all of your music with a range of analogue inputs and two digital inputs. High sound quality circuit design based on the ToP-ART (Total Purity Audio Reproduction Technology) concept ToP-ART Design and ART Base Ensure Optimum Sound When processing and transmission of the audio signal is simple and direct there is less chance of it being affected by noise and distortion. Yamaha’s amplifier design technology called ToP-ART features an I/O (input to output) Direct Symmetrical Design, with left and right channels organised in a straight, symmetrical layout for highest signal purity. In addition, the ART (Anti-Resonance and Tough) Base bottom chassis and a solid centre bar provide high-rigidity support and vibration damping. These Yamaha design innovations contribute to this amplifiers’ rich audio reproduction with abundant musicality. High Quality Parts for Outstanding Audio Performance Custom-made power transformer, custom-made block capacitors, two direct signal path speaker relays, one-point grounding system, aluminium-extruded heat sinks and other top-quality parts effortlessly handle demanding audio signal conditions. The quality of each individual part, as well as how they work together, basically determines the sound quality of any component. Yamaha uses only very high quality parts, carefully selected and tested. Created by Yamaha's Rich Experience and Tradition, and High Technological Expertise Yamaha, with a long history of over 125 years as a musical instrument maker, also has a high reputation for Hi Fi components. The A-S701 is created by taking advantage of this rich experience and high technological expertise. Based on the concept of “Natural Sound”, for reproducing all music as it really sounds, and built with scrupulous care from circuit design to basic sound production, even though an entry model it reproduces high sound quality and musically rich sound.
