Absolute DAC Hyperstream DSD, DXD DAC



At Ideon Audio we undertook the task of reaching the holy grail of digital sound reproduction… And to propose a device so highly performant, it will transform the information contained in source files into the absolute plausibility of live music, much as the best reel-to-reel master tapes and the best analogue turntables can do.

The Ideon Audio Absolute DAC is this device. The sonic end-result is beyond what any of us and any of our fans ever imagined is possible.

The sound is vast, superlatively confident; the sense of space and dynamic contrast are beyond imagination, reaching a superb sonic experience.

The Ideon Audio, Absolute DAC comes at a price; overall however, we feel that we have now reached and possibly surpassed the sonic merits of the outlandishly priced, top performing DACs at the top end of the audio constellation!
