These capacitors from ELNA provide true audio reproduction by the suppression of electrical noise caused by external vibration.  The ELNA Cerafine Series capacitors contain super fine ceramic particles which, through chemical reaction, improve the discharging speed between the anode and electrolyte.  The result is less sensitivity to externally generated noise due to vibration which ultimately results in less distortion and increased clarity.  Replace your existing power supply capacitors with these caps and notice the improvement.  We believe the ELNA Cerafines are as good as the Blackgates but are just a fraction of the price!
