Polarity
There’s a problem that has been ignored by the entire music industry which I believe is really important to music-lovers that I think you might want to investigate. Approximately 32 years ago when digital media was introduced to the music consuming public as a media with “Perfect Sound Forever” the music industry made a huge screw up when it got the playback polarity of digital music on CDs and later DVD, etc reversed (inverted polarity). On a random basis that means that digital media and files are heard in the wrong polarity approximately 85% of the time and either 92% wrong or correct once their audio and video systems are set to a fixed playback polarity.
The bottom line is that the music played in inverted polarity sounds harsh and two dimensional which is probable the major reason that some music-lovers still believe (without knowing the real reason) that analog music media (that plays in the correct polarity over 99.9999 +% of the time and would also sound bad if played in inverted polarity) sounds better than digital media, when in fact it doesn’t sound as good. That often causes music-lovers to spend untold sums of money and time trying to smooth out the edgy and somewhat irritating and flat sound of digital media. This should be an object lesson on how an entire industry with its experts and electrical engineers can get it wrong and not do anything about if for over 32 years and counting!
But there’s some good news here because in many cases, all one has to do is reverse the connections of all their speakers wires at one end only to correct the mistake that’s free for the doing. For more on how do that, see the homepage of my website: http://www.AudioGeorge.com and scroll down to just below the credit cards I accept. Many in the music industry agree with me. I’m know in the industry as The Perfect Polarity Pundit Chief Polarity Buster of the Polarity Police and come companies send me their digital media/components to check its polarity, and do that pro bono for the sake of the music. I’ve written two monographs that go into great detail about the problem at: http://www.ThePolarityList.com, http://www.AbsolutePolarity.com, and http://www.PolarityGeorge.com
