High sound quality circuit design based on the ToP-ART (Total Purity Audio Reproduction Technology) concept
High Quality Parts for Outstanding Audio Performance
Created by Yamaha’s Rich Experience and Tradition, and High Technological Expertise
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.
