the DAC. Using specially developed cutting-edge technology, it transforms digital signals

into pure worlds of sound - unadulterated, precise and full of detail. For connoisseurs, this

means Music in its most original form, made possible by the highest engineering skill and an

unmistakable sound design.

Amplifier

The Amplifier line-up consists of cutting-edge amplifiers that surpass the limitations of conventional

amps by incorporating the latest innovative state-of-the-art technologies. Our proprietary Class AD

maintains powerful damping power, the efficiency and power amplification characteristics of

traditional Class D amplifiers, while delivering pure, natural, and vivid sound reminiscent of analog.
