Yamaha A-S501 85W Integrated amplifier

The Yamaha A-S501 ToP-ART amplifier offers high sound quality with plenty of functionality and an elegant design. The A-S501 integrated amplifier also features digital inputs, handy for connecting digital source equipment (such as audio streamers and televisions). The ToP-ART (Total Purity Audio Reproduction Technology) design houses an audiophile audio circuit that you hear straight away through the connected loudspeakers, with 2x 120 watts (maximum) or 2x 85 watts (RMS) of output power available.

Pure Direct Mode for absolute sound purity is there for the true enthusiast, while variable loudness control is also at your disposal. The amplifier is further equipped with quality gold-plated speaker terminals, four RCA line inputs and one RCA phono MM input, plus two digital audio inputs, one coaxial and one optical. All in an elegant, sleek design with a handsome solid aluminium front panel.

Pure Direct mode for greater sound purity

The A-S301 is equipped for digital audio input with both optical and coaxial connections. The optical input is for receiving audio from a TV and the coaxial input for receiving audio from a Blu-ray player. The audio stays in the digital domain, giving you pure, pristine, dynamic sound for all your entertainment sources, from sports and other programmes to films and concerts.

Custom-made power transformer, custom-made block capacitors, two direct-signal-path speaker relays, single-point grounding system, extruded aluminium heat sinks and other high-quality parts effortlessly handle demanding audio signals. The quality of each individual part, and how they work together, essentially determines the sound quality of each component. Yamaha uses only carefully selected parts of very high quality.

Pure Direct mode ensures that the music signals take the shortest possible circuit route, bypassing the buffer amplifier and the tone, loudness and balance controls to eliminate virtually any signal degradation for the purest sound quality.

ToP-ART Design and ART Base ensure optimal sound. When the processing and transmission of the audio signal is simple and direct, it is less likely to be affected by noise and distortion. Yamaha's amplifier design technology called ToP-ART features an I/O (input to output) Direct Symmetrical Design, with the left and right channels organised in a straight, symmetrical layout for the highest signal purity. In addition, the ART (Anti-Resonance and Tough) Base sub-chassis and a solid centre bar provide high rigidity and vibration damping. These Yamaha design innovations contribute to this amplifier's rich audio reproduction with an abundance of musicality.
