Yamaha A-S301

A power amplifier with the advantages of digital inputs. The quality of the individual components and their interaction are crucial for the sound of each component. That’s why Yamaha exclusively uses high-quality parts that are carefully selected and tested. The A-S301 guarantees excellent signal reproduction even under demanding conditions. The power transformer and bypass capacitors are custom-made, and the speaker relays have a direct signal path. Additionally, there is a single-point grounding and extruded aluminum heat sinks. When the Pure Direct mode is activated, the signal bypasses the circuits for bass and treble control, balance, and amplifier buffering. This improves sound quality without affecting the maximum output power. Shortening the signal path enhances acoustic purity and allows for the reproduction of even the finest musical nuances. The ToP-ART concept (Total Purity Audio Reproduction Technology) ensures excellent sound in conjunction with the ART Base. Only when both the processing and transmission of audio signals are designed to be simple and direct can the influence of noise and distortion be minimized. The Yamaha technology for this amplifier design is called ToP-ART. It features a fully symmetrical structure from input to output, with the left and right channels processed with the shortest possible signal paths. This guarantees outstanding sound with unadulterated clarity. The ART (Anti-Resonance and Tough) Base housing bottom and the solid middle rail provide additional stability and dampen vibrations. These design innovations from Yamaha contribute to excellent audio playback with outstanding musicality.
