I think there is confusion between "asynchronous DAC" and "DAC with asynchronous USB input" here.
Yes, a DAC can run in a completely independent clock domain (from a clock completely isolated from the input), and this is fairly common these days. The problem is of course getting ahead or behind the output data stream. Asynchronous USB allows the DAC to regulate the flow of data from the source, but with other types of input this is not an option, so the standard solution is either to derive the DAC clock from the input data clock using a phase locked loop (that smooths out any jitter), or an asynchronous sample rate converter.
