Well, "clearly," it's not "seems impossible"; it's "is impossible."

The bumblebee thing was your claim; I was just correcting the wording of it.

It's
not beyond current scientific understanding; it's
logically impossible.
A digital cable can compromise digital sound quality in precisely two cases: when the cable is improperly made or is subjected to conditions outside what's accounted for in the spec. Both conditions are abnormal. They result in random distortions (or total failure) that are extremely obvious (often resulting in device malfunction) and have no specific or consistent audio properties (in digital audio transfer), due to the fact that the order and function of the bits in the cable has nothing to do with the meaning of the bits when reassembled into the data stream (e.g. audio, video, keyboard strokes, mouse movements, etc.).
As for the enhancing part, that's logically impossible. The cable is supposed to transfer a series of logical true/false values. In the kinds of cables we're talking about, this is done one bit at a time. Adding extra values, or removing values, would corrupt the data and change the meaning of the values that follow in a random and haphazard fashion. What you'd get in this case would be random noise. Enhancement through randomly changing the bits' values isn't possible because every bit is sent one at a time through the wire; any properties of the wire would affect all bits equally.
And of course the wire is just a dumb piece of metal, so there is no way for it to look at the bits, decide which ones correspond to the desired traits of the audio (e.g. soundstage, bass, midsection, brightness) and then just happen to start affecting bits when those bits happen to pass through. If you want any kind of digital enhancement, you need to look into something like better ripping software, a DSP (to improve the bits before or after they are transmitted), better DACs or ADCs in your components, etc.
A digital cable is just a medium for lossless transfer of binary data from one device to another. If it doesn't facilitate this lossless transfer, it's not functioning properly, period. There's no way to "spice up" the data. If your job, to be repeated many times a day, is to read a number on the screen and write the number on a piece of paper, then random changes to the numbers aren't helpful or even able to have a consistent result of any kind (unless you want to get fired and have a nasty hole in your resume).

Why not? What experiments have you done to make such a conclusion? Do you design or test digital equipment? What expertise do you have to make such claims? I guess I most want to know what authority has determined digital cables make no difference? |
What you're asking here is for me to
prove a negative.
