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.
