A close look at the insides reveals only the smallest amount of circuit board near the rear of the unit has DAC electronics. Everything else is power supply.
When we look instead at a SMPS we would see something very much smaller. Perhaps a tenth the size of what's in the picture of the DAC. The output DC voltage of both would be identical, the elements that make up the two supplies are the same, yet one is considerably bigger than the other. How can this be?
The first hint is this: while both supply types have the same elements, the SMPS has an additional element in front of the power transformer. This new element in the design is where all the magic happens and makes the miniaturization of the supply possible.
