Why does my DAC sound so much better after upgrading digital SPDIF cable?

While I am obviously impressed with this high end digital cable and strongly encourage others to audition it, I am puzzled how the cable transporting digital information to my DAC from my transport makes such a big difference.

Though the impulses are digital by nature, the way they are transferred through the cable is still electricity.  Some cables apparently do a better job at preserving the integrity of those digital impulses. I found the same phenomena to be true also with USB cables.  Once we get out of our heads that its only 'pluses and minuses,' we can begin to find out what sounds better for our taste in sound. People have become hindered by the "digital mystique" that started in the launching of the digital era. Its not only about +'s and -'s.

@audioengr thank you. what would you recommend for a toslink-to-mini-toslink convertor? For compatibility with an airport express or chromecast audio.

Thanks! 

You know I have no idea how I could possibly get to the end of this thread because of the utter rubbish that is being spouted. To the people who say that cables don't make a difference why don't you take all your cables that you have at the moment and replace them with cheap stuff that you Americans would say comes from a nickel and dime store and listen to your units for a whole week of at least two hours a day. Now after that is done get a mate to loan you some upmarket cables and do the same and listen to it for another week. If you don't notice a difference straight away and I'll give some of you two days time and it is not patently obvious to you that there is a massive difference then please take a tip from me and sell your stuff because you plainly cannot hear properly. I bet in all this time you have not even considered the people who are responsible for the content of your disc or file "the musicians" . I happen to be a musician myself and although I was never blessed with perfect pitch I know when something goes awry. say you are sitting in a recital hall and one of the players violins goes flat on a string then everyone instantly hears it even people who say they are tone deaf , but absoloutely no one is tone deaf. The same applies to high end music systems and that is why a lot of musicians don't listen to audio because they know it rarely sounds like real music, it is only a representation of real music. Why don't you do yourselves a favour and stop the carping because clearly no one will win.
