Yeah, they try to send a precise potential just to be sure, but in the end they check if it's above or below a limit because for sure it won't be exactly .2 and .6

And besides, even if we are having trouble telling 1 and 0 apart, then we'll have trouble figuring out any info since that's all we are reading. In other words, if all we're doing is looking for 1's and 0's, and we can't tell them apart, then we won't be seeing much.

Sure, most of the time the signal is clear, but as I said many things can happen that blur the distincition. That's when errors appear

Isn't the digital cable usually longer than any path inside the player?

Well, I would think that the path inside error-correction chips, and othes,r before getting to the DAC is relatively long, but I admit I don't know the exact numbers

You're mixing singal types here. Gold has nothing to do with light (though I've had a good laugh when I've seen gold plated optical cables in a hi-fi store!). Gold is better for transmitting based on electric reasons. It doesn't cororde as easily, it's a better conductor, it's more maluable, etc.

Sorry, it's you that is mixing stuff.
The gold I was talking about is on the disc itself, therefore it does relate to light.

It's alright, all done in a friendly and constructive manner!
Thanks!
