I agree with your first statement, but an input buffer (which all DACs - including those in CD players - must have in order to function) does nothing in itself to resolve this problem. You still need to generate a clock from somewhere, and if you use the transitions in the input for that you´re still sensitive to jitter. There are some easy but inconvenient ways to make a DAC that is completely insensitive to input jitter (for example buffer the entire input and then clock it out with a crystal), and some hard but convenient ways as well (see e.g. the Lavry whitepaper for the DAC10).
