New ELNA/Cerafine (ROA) Series/Audio Capacitor/330UF/35V Cerafine series capacitors specially designed for audio, using OFC oxygen-free copper feet, extremely low distortion (third harmonic distortion -120dB), very small tangent loss, using the technology of pouring ceramic fine powder in electrolyte, powder diameter control between 0.1-0.15 microns. According to the manufacturer, this technology has two major benefits: First, it increases the damping effect on external vibration. Second, when the filled ceramic powder is charged and discharged in the capacitor, it will absorb the negative ions in the electrolyte and become more active ion groups, forming a thin film on the surface of the anodic oxide film, which greatly improves the response speed to the signal and improves the sound quality. It is more pure and transparent, but its price is large and expensive. Sound: The sound is relatively soft, the mid frequency is warm and soft, and the high frequency is more gorgeous!
