The Reviews Are In

Describing the sound, a Head-fi reviewer writes, “Presentation is full-bodied and powerful, smooth and resolving, but still remains linear and carries across all the details present in the recording. The dual crystal oscillators with their variable native sample rate tackle any kind of format with apparent ease, rhythmic precision, and timing with everything from progressive psytrance to jazz instrumentals and hard rock."
