Features

World's Highest Analog Performance

The newly developed "DWA (Data Weighted Averaging) Routing Technology" suppresses noise caused by manufacturing process factors and achieves world-class analog characteristics (S/N: 135dB  per channel / THD: -124dB).

Ultra-Refined High-Resolution Audio Playback

In addition to adopting a completely separated digital/analog circuitry solution, the design was further refined based upon AKM's latest high-quality sound design techniques. The system reproduces all musical information, down to the most minute detail, to achieve a "sound as if you were there" experience.
