Now we just need an aural test that proves the same for digital transmission as that picture proves from an optical point of view.
I totally agree. You can do to a certain extent with software like audio diffmaker. However, it depends if you are talking digital or analogue. It's very easy to prove that digital transmission is the same as one end as it is at the other. The tricky bit comes in when you convert that into analogue so you can acutally hear it, and that's where the whole thing goes to pot.

If your eyes can't see that picture for what it really is, then how do we know what we are hearing (in certain circumstances) is correct?
We don't and I've admitted many times to hearing differences, then also being able to prove to myself those differences don't actually exist!
That's why I will always say listening to stereos is totally subjective and there's too many variables imho to have some kind of standard. But that works both ways, in that just because you have changed a cable and hear differences, doesn't mean there are any there.

How can you trick my brain into hearing something I'm not really hearing?
erm, stereo does a pretty good job of that
It's also important at this point to define this sentence. It's harder, but possible, to make the brain hear things that are not there, but moreso in the case of this things like cables, it's changes people go on about, not actual things that aren't there. So whilst there maybe no "real world" changes, people still hear them. It's the same thing they are hearing, as in nothing new per se is being heard, but because people are aware that something has changed they expect something in the music to change. It's actually possible to do this without changing anything, just listen to the same track a few times, and each time really focus on a different part of the music on each listen and it will sound different.
I'm not stopping anybody buying cables, if they want to, that's up to them, I'm just merely trying to say that in some cases there are no proven differences, so as a musician myself, I urge people to spend the money on the music, or going to a gig, rather than to perpetuate what is *in some cases* just a bunch of advertising in order to make money. Hifi would be pretty useless without something to listen to, and I'd rather people helped fund that which they say they love (the music) and not the snake oil salesman. Also, that in this merging of digital and hifi, that there are people out there who have been at it already and *do* know what they are talking about, so not ignore them out of ignorance because they are clinging on to rules which just don't apply any more. It still amazes me the amount of people who are willing to spend hundreds on cables, yet won't even consider the most modest of room treatments which would innevitably bring much more sonic goodness.
