S-Master digital amplifier: true sonic purity

Enjoy the best of digital audio with the S-Master digital amplifier. Using a simplified, full digital signal path, the S-Master amplifier reproduces digital audio signals without the multiple analogue stages required by conventional amplifiers. The result is not just more power, but significantly less distortion caused by heat build-up.

DSEE restores detail to your digital music

Boost the quality of your compressed music files. When an original music source is compressed, it loses the high frequency elements that add detail and richness to your favourite tracks. The Digital Sound Enhancement Engine (DSEE) faithfully restores these to produce high quality sound that’s closer to the original recording.
