The Orchid uses Phillips TDA1541A-R1, which is the top of the line DAC from that Phillips 15xx series, compared to the lower cost TDA1545A chips used in the Canary. The Orchid uses an OPA861 transistor for output gain whereas the Canary uses additional TDA1545A chips for output gain. This link below summarizes all differences;
