Okay, now you got me going:
"All of the problems with digital are analog problems."
Not true. There are a whole class of problems that are uniquely digital. Its like saying the signal issues with termination of a digital signal are the same as with an RF signal. Not really. For example, in the RF case you care about VSWR or voltage standing wave ratio (amplitude of reflection). In Digital, we care about timing of reflections as well as amplitude. The delay along the cable is important in Digital.
It is true that all digital signals are essentially analog first.
"in ANY digital system, it is rare that the errors are so large that there will be actual corruption of the data"
This I agree with. There are tons of posts on the forums from people that believe there are errors. Maybe reading a CD, but not transferring digital data.
" it turns out that far more important than the absolute amount of timing error is the spectral distribution of the error (ie, how much error is there at high frequencies versus low frequencies), and whether that timing error is correlated with the audio data (music signal) or if it is just random variations"
I also agree with this.
Its interesting that Gordon did not address the reasons why Async USB interface is imperfect, ala common-mode noise....

Well, Steve, I don't think it is a big secret that these fellows are very brilliant, but VERY opinionated as well.
I have a lot of respect for Charlie Hansen, but he does come up with some odd stuff on occasion.
I have never heard Wavelength products, but I know Mr. Rankin has been marketing async USB as the cure all
for everything, so not a surprise he does not address its shortcomings, what ever they may be.
