Jensen make 4 different types of copper foil capacitors, all with the same internal make up but fitted inside different enclosures. We have the lower cost aluminium can, highly popular for those on a budget. Then we have the copper can type, probably the more well known of copper foil types, then the paper can type and ceramic can type. All these enclosures offer slighly different characteristics to the sound. The paper can version is beautifully smooth sounding, with great detailing and presence, a real hi-end sound. Fitted with pure silver leadouts, 1mm diameter, 50mm / 60mm length.
