Multi-Path is a profoundly new audio D-to-A conversion architecture that improves today's best DAC performance by 100X (40dB) or more. Noise, Linearity, and Dynamic Range are so advanced that today's finest test equipment cannot fully measure it (40nVrms broadband noise floor). This 100X breakthrough represents the greatest single objective improvement in the 140-year history of audio technology.

In brief, Multi-Path topology breaks an incoming audio signal into 2 or more dynamic pathways. The lower pathways are managed for extreme low noise, while the higher pathways are managed for extreme high levels. Combining these pathways results in an audio dynamic range in excess of 28-bits, or 170dB. Today's very finest DAC's rarely achieve anything close to 130dB. These improvements are entirely a result of a profound reduction in electronic self-noise (reducing today's common 4.0uV to an astonishing 40nV, broadband, unweighted).

This technology has been in R/D for >10 years and was recently awarded three U.S. patents, along with foreign patents. The technology is now in beta testing with 50 of the world's top audio mastering and mixing engineers, with unanimous adulation. If all goes well, we should be shipping product by mid-2025.

An Audio Engineering Society (AES) peer-reviewed engineering paper is available for a deeper dive into this technology. Paper # 21106 (search at aes [dot] org).

There is also a 3-minute video that gives a very brief overview of how the technology works (linked to this entry).
