On a polyphonic system, asynchronous clocking requires a separate DAC per voice. Mixing/summing is then done after the conversion in the analog domain.
Hardware-wise, this is of course a very expensive way of implementing a sample playback engine. However in the early days of sampling that was the only way to do it, simply because high-quality realtime interpolation wasn't feasible.
That's why e.g. the Synclavier had separate voices, each with their own DAC.
This is not how the Solaris works. In fact, I don't believe any modern system works that way anymore.
