Sound Technology

From WALKMAN® to high-end audio equipment, Sony’s sound technology and innovation continues to define—and redefine—the listening experience.


Sony's full-digital amplifier preserves the original signal, resulting in sound that is exceptionally rich and faithful.


S-Master amplifies digital signals without D/A conversion, thus maintaining the purity of original signals for highly faithful reproduction.
