No, I don't, and I wouldn't say so. Much of what you have said is in fact true. It just doesn't apply to the current discussion.

But clearly you didn't read the previous monstrosity very well. Could you point out precisely which part of the thread was not about digital?? I have just re-read it and found only a very small amount of information that related to analogue interconnects. A VAST chunk of it deals quite obviously and specifically with the digital medium. Can't be bothered to cut and paste which bits as there's far too much info and it will clutter up this thread still further...

The problem is that, in both the huge post you refer to and what you've said here, all the talk is about analog to digital conversion and digital to analog conversion. And again,
those don't apply here.
The huge post in the other thread spends the first half talking about cable qualities. It even says that impedance mismatching is a digital problem. It is in fact just a general transmission line problem. But it's a big problem for analog because in analog form, the exact level of the voltage is used to create the sound/video/information. But when we enocde that infromation in digital, there's only two voltage levels we care about. Those two voltage levels correspond to 1 and 0. As long as we're able to tell the difference between the two, we can piece back together the information. If we can't tell the two apart, then we get nothing (we're either seeing all 1's or all 0's).
Then there's the second part of the huge post. It goes into great detail about the problems with converting analog audio information into digital form. Great, it goes into very in depth and thoorough information and looks good to me. The problem is that all that infomation is not germane to this discussion. All of that analog to digtal conversion is done by the time we're popping in a DVD/CD into our players and reading information off of it to send down our digital connections. Let me repeat that because it apparently needs repeating: all of that talk is moot by the time we get to what we're talking about. There is
no analog to digtal (or vise versa) conversion going on between reading the information with a laser off of the disc and your receiver getting it over the digital connection.
Again, I'll point out here that most of what you mention in this thread Tyler also has nothing to do with this discussion. You're either talking about A/D or D/A conversions or some disc mastering problem. We're talking digital connections and you're bringing up analog aspects. They don't come into play here. Sorry for repeating that so often in this post, but it doesn't seem to be getting through.
Anyway, give me some time and I'll attempt to comeup with some basic explanations of A/D, transmission line qualities, digital signals, etc.
