One may be shocked to learn that 1212M and 1820M use hi-quality converters and high passport parameters of inputs and outputs, that exceed even the measured characteristics of Lynx L22/Lynx Two soundcards. The models have the same ADCs as Lynx, but their DACs are newer (4398 vs 4396). Although certainly, much also depends on the quality of the quartz, operational amplifiers, and the layout
