הכוכבית של הנסיך הקטן, b612, לא הייתה ידועה. בתחילת המאה הקודמת גילה אותה אסטרונום תורכי, וזה הציגה אותה בפני באי כנס בנושא. ברם אולם, איש לא האמין לו, שהרי האסטרונום היה לבוש כדרך התורכים אז: שרוואל ותרבוש.
"למזלה של הכוכבית b612" כותב דה אקזפרי, "קם בתורכיה שליט תקיף" וזה חייב את בני ארצו ללכת בלבוש המערב. או אז חזר האסטרונום לכנס בנושא, לבוש חליפה, הציג שוב את הכוכבית וכולם שמחו לשמוע ממנו על קיומה של הכוכבית b612.
עכשיו, כאשר יש מדידה וגרפים, ישמחו "המדענים" שבחבורה לגלות כי אכן כבלים משפיעים על איכות הצליל.

Cable manufacturers Nordost and Vertex AQ had good reason to present their joint seminar, "New Approach to Audio Measurement: Why Cables Really Matter," no less than five times during the show. As Art Dudley will report at length in his December "Listening" column, their groundbreaking new approach to measurement, developed by Nordost and Vertex AQ in collaboration with military electronic-engineering consultant Gareth Humphrey Jones, has produced an entirely new method for measuring the audible effects of components on sound. We're talking not only cables, support platforms, and the like, all of which can now be unequivocally shown to affect a system's sound quality, but also CD players, amplifiers, and speakers.
Co-presenters Roy Gregory of Nordost (former editor of HiFi+) and Steve Elford of Vertex AQ (pictured) projected a series of graphs that for the first time definitively demonstrated the effects of audiophile power cables, supports, and the Quantum device on sound. They also measured differences between CD players. Simply changing from a stock power cord to a well-made audiophile cord resulted in a 36% reduction in timing errors between the original WAV file and the same file burned on to a CD and played back by a typical high-quality player. Vertex AQ's support platform further reduced noise by 15%. The Quantum unit reduced noise by another 11%. Furthermore, there was no apparent hierarchy; if the support platform had been introduced first, rather than the power cord, its effect on errors would have been far greater.
Errors and effects that were formerly attributed to jitter have for the first time been identified as program-related using real music as the test signal. These errors cannot be identified by the standard continuous tone tests that everyone and their mother have been using all these years. To quote Roy Gregory, "We knew this stuff worked, but we didn't know why. Now we can gain insight into how to construct cables, CD players, and amps to produce better sound."
According to Gregory, the so-called law of diminishing returns, which says the more costly, high quality parts you put into a cable or device, the less of an improvement you will hear, need no longer apply. Using this new form of measurement to perfect products, it should now be possible to mate properly designed cables, components, and supports to deliver sound that reflects every bit of the time and investment devoted to their design and manufacture. This will not happen overnight—developing these measurements took a good six months, and this is very much a work in progress—but the results so far are extremely heartening. Bravos and gratitude to all.

בתערוכת RMAF הציגה חברת הכבלים נורדוסט שיטה למדידת כבלים והשפעתם על מערכת השמע, השיטה, שפותחה בשיתוף ורטקס, הודגמה בתערוכה (להלן קישור אחד מכמה http://blog.stereophile.com/rmaf2009/).עכשיו, כאשר יש מדידה וגרפים, ישמחו "המדענים" שבחבורה לגלות כי אכן כבלים משפיעים על איכות הצליל.
