Yamaha A-S501 Integrated Stereo Amplifier
Yamaha, with a long history of over 125 years as a musical instrument maker, also has a high reputation for HiFi components. The A-S501 is created by taking advantage of this rich experience and high technological expertise. Based on the concept of “Natural Sound”, for reproducing all music as it really sounds, and built with scrupulous care from circuit design to basic sound production, even though an entry model it reproduces high sound quality and musically rich sound.
The Pure Direct mode causes the music signals to travel the shortest possible circuit route, bypassing the buffer amp and the tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.
