If you read much promotional literature for recently introduced high-quality equipment, you'll notice a common theme emerging: balanced connection. Balanced inputs and outputs are becoming a must for any audio equipment that has any claim to quality. The word itself has promotional value, suggesting moral superiority over the long-established "unbalanced" connection (for the purpose of this discussion, I will call this "normal"). What's my problem with this? Simply this: The High End could be paying dangerous, costly lip service to the received wisdom that balanced operation is the goal for an audio system.

<I>More than 20 years ago, when the turntable was considered a perfectly neutral component in the playback chain, Ivor Tiefenbrun single-handedly demonstrated to the world that the turntable was not only an important part of a hi-fi system, but perhaps the </I>most<I> important part.

The future is rarely what anyone expects it to be. I still remember reading, as a child, predictions in <I>Popular Science</I> that everyone would have a personal helicopter by 1980. It never happened, though it sure seemed like a reasonable projection of events. Events, however, have their own agenda.

During a recent visit to Canada's National Research Council, I noticed stuck to the wall of the prototype IEC listening room a page of results from one of Floyd Toole's seminal papers on the blind testing of loudspeakers. The scoring system was the one that Floyd developed, and that we adopted for <I>Stereophile</I>'s continuing series of blind tests. "0" represents the worst sound that could possibly exist, "10" the perfection of live sound&mdash;a telephone, for example, rates a "2." The speakers in Floyd's test pretty much covered the range of possible performance, yet their normalized scoring spread, from the worst to the best, was just 1.9 points.
