Cable burn-in: an acknowledged problem in need of a better solution.
It is a well-known fact that high-quality audio and video cables
improve over time when used in a hi-fi or home cinema system. A
hard, closed-in sound with a distinct lack of bass are the qualities most noted when a cable is new; a cable that has been burned-in will sound more open, extended and three-dimensional, with a more natural, less sterile performance overall.
Unfortunately, most high-quality specialist cables only get close to
realising their full potential after months of use. Playing widebandwidth
music gradually improves the performance of speaker and
interconnect cables, yet technically they will never reach optimum
performance with music signals alone.
The problem is quite simple. Real music has very little high-frequency
energy, and thus will have a limited ability to improve a cable.
Research shows that musical instruments may produce energy above
20kHz, but there is little sound energy above 40kHz. Also, most
microphones do not pick up sound at much over 20kHz.
Furthermore, even the best burn-in CDs have a limited effect, owing
to the limited frequency range of a CD player. A typical CD player has
a sampling rate of 44.1kHz (Red Book standard). Digital theory
(Nyquist) suggests a maximum frequency of 22.05kHz; the highest
frequency is always half the sampling frequency. In reality, 20kHz is about the maximum because of the need to filter within the replay device.
