DA conversion

For each channel a separate PCM63-K is used. These converters have 20 bit accuracy and can handle an 8-time oversampled clock. A special "colinear" conversion technique is used to obtain extremely low distortion. The "K-grade" is a selected version which has even better specifications.

Implementation considerations,

All supplies have been separated (see power supplies section) and locally decoupled

We tried to use the offset current sink, but we also couldn't hear any audible difference when not used.
