Loads of PCs have a digital audio output (may be coax or optic) and you are completely correct in that they can replay the audio CD from hard disk or whatever and still be bit exact. The jitter is a factor of the quality of the clocks in the PC audio I/O... but there will always be some. The above circuit would work exactly the same sitting between a PC and the DAC, and improve the jitter in just the same way. | |

I should probably ask a separate question, but ... under discussion is digital info coming from "a CD transport". the thing is, these days you can just move the exact unchanged digital data to "the ram in a computer", and throw away the transport and the CD. Then, i guess, the exact same data can be piped? to the DAC. In that case, RogerLucas, is jitter then nonexistent, an irrelevant paradigm? Or do I misunderstand? Thus, for actual Hi Fi Nuts of today as we speak, do they never ever use actual CD transports? they just first pop the data on to ram? TY! | |
