The trend towards high-resolution audio has attracted people's attention to the high-frequency range, but in reality, the advantage lies in the low-frequency range. This is because it can express tone and showcase performance techniques clearly, not just a matter of volume. For example, the melody of "Ode to Joy" in Beethoven's Ninth Symphony was originally played by the low cello and bass, why is that? It is because the melody had been gradually hinted at through numerous fragments before being concentratedly expressed by the low instruments at the end.

Perhaps Beethoven's true intention was in the low frequencies. Such thinking can guide our exploration of sound quality. When you replace a good audio cable, it becomes very clear and bright. Now, even the material of the audio cable can visualize its crystal orientation. By using high-precision field-emission scanning electron microscopy (FE-SEM) with equipment equipped with energy-dispersive X-ray spectrometer (EDS), it has successfully explained sound differences that cannot be explained by other means from the perspective of "directionality," such as purity and grain size, and has been reconstructed during the processing and heat treatment of the copper wire.

Acrolink's latest 7N-S1040 Leggenda product has made greater progress while inheriting the design concept of the S1040 series. Using Acrolink's exclusive D.U.C.C.7N Cu, the bi-directional wire treated with pressure relief produces instantaneous sound effects at a speed of 0.37 P 50 strands, and is twisted at high density in both right and left directions, and then insulated with Acrolink's proprietary polyolefin material to make it a structure resistant to noise. Then, these two wires are integrated together and wrapped with a high polymer polyolefin dielectric layer containing tungsten and amorphous materials to achieve better vibration damping and electromagnetic wave absorption effects. Finally, copper foil is used instead of a grid for shielding to make it more aesthetically pleasing.

This audio cable can display the movements of each string instrument in the orchestra and has precise expressiveness with high resolution and small signals. It can accurately reproduce the performer's techniques and present the true face of music. High-resolution clear sound imaging and deep low-frequency tone, broad frequency characteristics, and dynamic range can reproduce the clear position and tone color, as well as the focus of the instruments in the orchestra. This unique shielding effect will ensure that the sound quality is not disturbed, and this is also a new "discovery" legend.
