<p>The amplifier design technology from Yamaha is called ToP-ART which features an input to output with a direct symmetrical design. ToP-ART design and ART Base ensure optimum sound when processing and transmitting the audio signal. The signal is simple and direct, therefore it is less likely to be affected by noise and distortion. The left and right channels are organized in a straight, symmetrical layout for the highest signal purity. In addition, the ART (Anti-Resonance and Tough) Base bottom chassis and a solid center bar provide high rigidity support and dampers vibration. These design innovations contribute to this amplifier's rich audio reproduction with abundant musicality.</p>
<p>Notice the custom made power transformer, custom made block capacitors, two direct signal path speaker relays, one point grounding system, extruded aluminum heat sinks and other top quality parts to effortlessly handle demanding audio conditions. The quality of each individual part, as well as how they work together, basically determines the sound quality of this component. Yamaha uses only very high quality parts, carefully selected and tested for their sound properties.</p>
<p>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 &ldquo;Natural Sound&rdquo; for reproducing all music as it really sounds, this amplifier is built with scrupulous care from its circuit design to basic sound production.</p>
