If you were an engineer with experience designing DACs, you would know that its not that simple. If you put layers of PLLs in the DAC, then you have the jitter of those PLLs. If you put a resampler in there, then you have those audio artifacts.
The best solution IMO is to leave the D/A alone and feed it the lowest possible jitter source. That source may be externally generated or internally from an async USB interface or network interface, both using fixed frequency clocks, not PLLs.
What you evidently dont get is that it's the fixed frequency clock with low jitter that is the key to the best possible digital audio result. Its not about some DAC rejection circuitry.
