"Steve, I thought DAC's suppose to clean out jitter or re-clocks them?"
This is only a relatively recent development. In the past, most DACs did no reclocking whatsoever. Like Edorr said, only a handful try to do this right now. Most use asynchronous hardware resampling to accomplish this, which generally results in sonic coloration and jitter from the clock they choose. None of them actually accomplish the goal of making the DAC jitter immune IME. I have modded a LOT of DACs in the past.
"There are some exceptions to this, in which the DAC buffers and reclocks ALL inputs (asynchronous DACs), most notably the PS audio perfectwave MKII in native X mode."
Pretty good, but several customers are still using Off-Ramp 5 to drive PWD even in NativeX mode. The dCS is probably the best at minimizing input jitter effects.
