Hei, gikk på hjemmesiden til Auralic og fant dette:AFN402™ Material
Through long-term research and test, we find out that audio signal could easily be disturbed by electromagnetic interference and get distorted. Such distortion could lead to the lacking in the sense of natural liveliness and smoothness of the music replay. The protection from traditional aluminous or ironic cabinet to audio signal is very limited. Therefore, in the times of CD as the main music player, the tiny details in music could not be represented fully as a result of the limitation of electricity properties from recording media and replay equipments. Along with the gradual widespread of Hi-Rez format music, the characteristics of replay equipment, the abilities of discovering and reproducing tiny details of music in particular, became the bottleneck of the whole system’s development. Also, external electromagnetic interference, for the 1st time, turned out to be the heart of the matter.
In order to satisfy the needs of Hi-Rez format music replay, AURALiC researched and developed a kind of cabinet material named AFN402, which is an alloy of iron with certain portion of nickel, silicon and other rare metals. AFN402 could not only isolate external electromagnetic interference effectively and efficiently, but also restrain resonance. The isolation ability within audio frequency and above audio frequencies from AFN402 turned out to be 3 times and 10 times of that of traditional cabinet respectively. De sier at de had laget et nytt cabinett materiale som er stål og aluminium overlegent. Jeg tror ikke at man kan spare inn 1.9kg bare på cabinetet, så de had non spart inn andre steder også. Alt dette spiller forsåvidt ingen rolle hvis forsterkeren innfrir.
