If the rumors hold true, the next iPhone, iPhone 7 or whatever Apple calls it, will not have a headphone jack. As Chicken Little noted, "The sky is falling!" Or is it? Is it possible, just possible, that losing the headphone jack could net us a nice step forward in audio playback quality?

Your daily driver is a Bugatti. Your "casual" wristwatch is an Audemars Piguet. (Note: Rolexes are for tourists.) Your third home is in Jackson Hole. I hate to break the news to you, but you are a 1 percenter. Fortunately, now you can drown out the cries of the masses with a superb new loudspeaker from Devialet.

A couple blogs back, we discussed the ascent of glorious stereophonic sound in “The Rise and Fall of Stereo (Part One).” Stereo was a true revolution in audio playback, and it quickly condemned monaural to an eternity of lo-fi hell. Audio manufacturers’ marketing departments had an easy time convincing consumers to upgrade to stereo; everyone could easily hear the improvement. Now, 50 years later, stereo is unraveling.

In the beginning, Edison created the phonograph, and it was good. It was also monaural. The vertical modulation (referred to as hill-and-dale recording) of the groove neatly encoded the amplitude variations of the analog-input waveform and likewise could reproduce the waveform. If engineers had stuck with hill-and-dale, the world would be a very different place. But they kept tinkering, as engineers are wont to do, and they found an improvement.
