Revolution 2×2 is built with the most cutting edge, high-end ICs. High-end Vishay, Nichicon, and Wima capacitors are used throughout the entire circuit. All internal gain-staging has been optimized for the very lowest signal-to-noise ratio. All of the analog I/O has not only been built with the finest components, but are fully decoupled and balanced — right to the very core of the convertor! Most manufacturers do not follow this practice, and that allows extra noise contamination during both capture and playback.
