Korg's new 1-bit stereo recorder, the MR-2000S, looks almost as good as it sounds.
The MR-2000S goes beyond the 1-bit/2.8224MHz format used in creating Super Audio Compact Discs and allows 1-bit/5.6448MHz recording, which, says Korg, preserves the clarity, ambience and true dynamic range of the original sound source with unprecedented accuracy.
