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

RE: Jitter vs sampling rate.

Doubling the clock frequency will, all else being equal, double the uncertainty in the sample value due to timing errors (this might be much less than any uncertainty due to amplitude errors). But, because you have doubled the sample rate the timing error per sample will be averaged over two of the smaller sample periods so, in terms of the original clock frequency, you are back where you started.
