Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

RE: Jitter

Jitter is a very non-linear form of distortion, and not harmonic at all. There is also a non-linear relation with signal amplitude in PCM encoding, because there are large numbers of bits changing at different signal levels. In fact, the worst jitter often occurs around the 0 level with the PCM twos-complement encoding because all of the bits change from 0 to 1. These changing bits on the data line are easily coupled to the clock in the form of data-correlated jitter (often thought to be the worst form) because of return path impedances (among many other mechanisms).
