If you are saying that jitter is irrelevant on playback until it's time to convert to analog, then I agree. If you're trying to say something else then I miss your meaning entirely.

HowdyI think he's obliquely saying that perhaps the improvement some hear from hi-res is due to better error correction.
He's wrong. It is true the audio CDs have worse error correction than data CDs. It's too bad that this is the way it is, but it isn't the end of the world since uncorrectable errors aren't that common on Redbook.
I read his post as a lamentation that SACD and DVD-A have the same poor error correction as audio CD, which is less than that of a data CD.Which is wrong. The error correction on the hi-rez disks is an order of magnitude greater than that of the audio CD. Don't know how it compares to a data CD.
HowdyI'm pretty darn sure that SACD and DVD-A both build on DVD tech and hence both have at least as good of error correction as DVD's data. Don't quote me tho :)
I think she has analyzed the file structure on an SA-CD and noted that essentially it's based on UDF but with the TOC deliberately corrupted so that a DVD player or a PC can't read it.But I think the salient point is that on DVD-* and SA-CD, audio/video is treated no different from data - they are stored as files on UDF and the player is supposed to provide enough buffering to stream it to DACs.
