This technology HAS NO DAC.
@tvrgeek If this is so, then the amplifier is not also class D. Class D is a very specific class of operation. Since you apparently have a degree, then you know that class D was proposed in the 1950s and the first home implementations were sold in the 1960s. You also know the building blocks required. So pick one: if its class D then it has a DAC built into the same box to which the digital signal arrives prior to the class D circuitry and probably one the same board as the class D section.
If this is false then its not a class D amplifier inside although it might employ switching technology.
