While this is an interesting argument I'll have to add something you may not have considered. Jitter and timing to the digital signal. Today's digital devices use edge triggering to read the data. Cables change the rise time of the edges, and they do so in uneven ways depending on the frequency. When the rise time changes the angle of the slope changes and this means that the threshold of the edge changes in time. So as the signals come down, the point in time where they are recognized as a 1 or a zero moves with varying rise times and this causes the signal to be jittered. I don't have time this morning to go into depth but this is just one (major) way a cable has a significant effect on the way digital "sounds". Trust me, it's not hype.
