Ideon Audio Sigma Wave USB Isolator - High-Speed Digital Audio Noise Filter | Perfect for Audiophile Systems & Professional Studios

Achieving a pitch-black background in music hinges on the complete elimination of digital noise, primarily through the digital power supply ground, which serves as the final signal ground. Our range of products—including Master Time, EOS Time, Absolute, and Absolute Time Signature — establish an optimal path for USB data transmission by re-generating, re-clocking, and re-driving the stream, minimizing distortion. Despite our rigorous efforts to minimize internal equipment noise using multiple ultra-low noise power supplies, it’s challenging to entirely eradicate the low-level noise inherent in the data stream’s generation at the source.

The Σigma Wave USB isolator.

To effectively eliminate these subtle yet impactful amounts of both electrical and digital noise and enhance final sound quality, further enhancing the results of the re-clocking function, innovative approaches were required. Leveraging one of the latest full USB signal isolation devices, combined with our uncompromising approach to quality, led to the creation of Σigma Wave.
