True, I'm in Dan's camp as far as clocking from outboard sources, it's really only needed when linking multi-devices. I've always thought that clocking from the source of the audio made more sense and in the olden days, it provided a more stable system for most of my apps involving only 2 or 3 devices in the clock chain.

If you look at page 8, upper right (digidesign article) it says:
"Internal clock provides the lowest jitter in a single interface system".
So the digidesign article supports what I have been saying.
The article states a lot of other facts that I have been saying for a long time, though I was not mentioned in the bibliography of that paper.
It would have been great to have Digidesign support a year ago, during my back and forth with that "other company" that makes clocks. I did not really expect Digidesign support, given all that I said about 192KHz, which they were selling at the time.
It would be worth noting that the new digidesign product, the Venue, is basically a 48KHz rate unit. It certainly does not support 192KHz. How does Digidesign explain it? I guess I will have to wait a year or 2 (similar to the clocking issue) for them to come around with a paper stating that 192KHz is not really needed, again, rehashing all that I said as if it were discovered by them.
Meanwhile, all my efforts regarding proper clocking ended at Saloon. My technical comments, posts and graphs are surrounded by posts about drunk monkeys and political junk.
One PSN moderator put the thread back on my forum, and the next day another moderator put it in Saloon. I consider putting the thread in Saloon very offensive. PSN has been ignoring the emails regarding the matter.
You can see the "Proper Word Clock Implementation" thread at Saloon:
