The mythology around cable upgrades in audio is old and pervasive. Mostly, it has been around so long many people assume that it is backed up by fact, but really, it is not. But it is complicated by one factor... what we hear, is affected by what we see (and know, and expect - see the McGurk effect http://en.wikipedia.org/wiki/McGurk_effect).
So there have never been any objective tests that show audible changes with cables. No measurements or double blind tests to back up the position taken by the cable believers. Only when they know that a cable change has happened (and which cable is being used), do they "hear" differences. But it is tricky because of the way our brain works, they actually do believe they hear this. It's not the same as placebo, but it is also not really reflective of any audible improvement imparted by the cable. And since they (and others over the years) do experience the same thing, the mythology persists.
Ultimately, for me, the takeaway is this.
1. There is no science or reasonable theory to support the idea of cables having any effect.
2. There is no objective test which has yet shown cables to have any effect.
3. Even if there is some subjective effect we "hear" as a result of these other biases and phenomena, we are at best chasing that last half of a percent of performance from our rigs. Money spent on cables (aside from usability and aesthetic decisions) should probably wait until the VERY end, when you have already maxed out the possible performance of every other component in your line. If ever.
