Cerafine ROAThe series are ELNA capacitors specially designed for audio, using OFC oxygen-free copper feet, very low distortion(Third harmonic distortion -120dB), Very small tangent loss, using the technology of pouring ceramic powder in the electrolyte, the powder diameter is controlled between 0.1-0.15 microns. According to the manufacturer, this technology has two major benefits: One is to increase the damping effect on external vibrations. The second is that the poured ceramic powder will adsorb the negative ions in the electrolyte and become more active ion groups when the capacitor is charged and discharged. A thin film is formed on the surface of the anodic oxide film, which greatly improves the response speed to the signal and makes the sound quality It is more pure and transparent, but its price is large and expensive. The sound is softer, the middle frequency is warm and soft, the high frequency is more gorgeous, and the fog is slightly heavier!
