Audiophile people go on war against coupling capacitors, considered as designing aberrations. However, it is often impossible to leave them. That is then very important to find the one who causes least losses, the one who degrades least the audio signal which crosses it.
LEFSON designed three lines of coupling modules, the C-MOD (Coupling Module), to resolve this problem. The C-MOD does not color and does not almost degrade : it protects the characteristics of the audio signal which crosses it.
It thus becomes possible to considerably improve the audio quality of a majority of gears, while keeping their characteristics, their features, their original sound color.
