Question:

Why not use a battery for the digital schematics as well?

LessLoss Reply:

We did use a separate battery for the digital schematics in the past, but the quality in sound reproduction can be even better by using a separately well-filtered power supply from the city mains. This has to do with the fact that in the digital schematics, unlike in the audio portion of the schematics, there is no provision for a balanced power supply. We still use two batteries in balanced configuration for the audio portion of the DAC 2004. But the digital section has no provision for balanced power (there are simply no parts that will use it) and the schematic therefore requires a single-ended power supply. However, what we do goes over and beyond what a typical battery-DAC can do, because we galvanically separate the digital section from the analogue section. This is the best possible solution to all problems of digital noise winding up in the audio signal. No battery can offer what galvanically separating the grounds in a DAC can achieve.
