ELNA is an earlier electrolytic capacitor manufacturer in Japan for more than 60 years. Using different color case packages between different models, ELNA supplemental capacitors are Cerafine (red robe), Duorex (purple robe), Longlife (silver word), Silmic (brown), For Audio (gold word on black background), For Hi-Fi (gold word on black background), STARGET (purple and red robe), RJH/RJJ (for filtering low resistance series) several.

  Among them, Cerafine and Duorex show a transparent tone; For Audio sweet tone; STARGET musical flavor; Longlife and Silmic performance fast and powerful, suitable for the performance of modern music. sony's CD machine often uses ELNA capacitors as a filter and coupling, Marantz, Yamaha, Tianlong, Yajun and other good amplifiers often use ELNA capacitors.

  SILMIC series is the audio design capacitor, is ELNA nice audio capacitor. Use OFC oxygen-free copper feet, small distortion (third harmonic distortion -120dB), very small tangent loss, natural silk fiber media, good sound, play silk soft naturalness, reduce the sonic oscillation design, increase the low frequency thick volume, reduce the high-pass part with peak Peak feeling and the rough sound quality of the middle frequency part.
II generation is the product of I generation, the overall performance is good, sound performance is good.
