High-Resolution Audio delivers premium sound

From source to speaker, Sony has brought together an array of technologies for the ultimate audio experience. For High-Resolution Audio files, the digital amp and specialized tweeters reproduce every subtlety, so you hear each note as the artist intended. For MP3s, digital processing software upscales compressed music to restore lost detail.

S-Master HX™ Digital Amp for pure sound quality

The built-in S-Master HX™ Digital Amplifier helps bring out the best of your High-Resolution Audio. It does this by reducing the noise usually heard in the high-frequency range, so you can enjoy clear, sharp sound.

DSEE HX™ technology upgrades compressed files

DSEE HX™ (Digital Sound Enhancement Engine) technology upgrades the quality of your compressed music files. When an original music source is compressed, you lose the high-frequency elements in the music. DSEE HX™ restores this to produce high quality sound that’s closer to the original CD recording.
