Paul, it's very simple. Two of the six DAC's are used to convert the left and right channels from digital to analog in the ordinary way. Then, special anharmonic filters are employed to tighten bass, smooth out edginess and reveal inner detail. The second pair of DAC's is now used in reverse to convert these processed signals back into digital format, where a multichannel, interlaced, shift-register filter, with arithmetic co-processors, extends the frequency response from below dc to above 200kHz (golden ears have been known to tarnish with anything less). Finally, DAC's four and five convert the enhanced signals to analog format, into auto-filtering, multi-stranded giga-cable, and out to the rhapsodic inputs of your digital-ready preamplifier.
