Impressive sound quality with a variety of features and an elegant appearance. A power amplifier with the advantages of digital inputs.

Yamaha not only has over 125 years of tradition in instrument making but also an excellent reputation for its HiFi components. The development of the A-S501 fully utilized both long-standing experience and technical expertise. Based on the concept of "Natural Sound," music is reproduced as it truly sounds. Moreover, the amplifier has been built with the utmost care from the signal paths to sound generation - even as an entry-level model, it boasts excellent sound quality and unique musicality.

The quality of individual parts and their interaction are crucial for the sound of each component. Therefore, Yamaha exclusively uses high-quality components that are carefully selected and tested. The A-S501 guarantees excellent signal reproduction even under demanding conditions - the power transformer and bypass capacitors are custom-made, the speaker relays have a direct signal path, and it features single-point grounding as well as extruded aluminum heat sinks.

The A-S501 features a new analog loudness control located on the front panel. It uses electronic volume control for the highest sound quality, allowing the loudness effect to be adjusted as desired. Separate from the normal volume control, this allows for influencing the balance between highs and lows. As a result, the complete tonal range is available, compensating for the natural hearing loss of high and low frequencies at low volumes.
