ClarityCap MR Range White Paper (download)
The MR range of capacitors is the result of an extensive ground
breaking 2 year research programme into audio grade capacitors.
The resulting capacitor is, we believe at the leading edge of today’s high quality audio grade capacitors.
The component is manufactured in such a way to substantially reduce the
negative effects of resonance on sonic quality which is inherent in a wound component. This results in a sonic characteristic which is difficult to equal.
Manufactured from metallised polypropylene film the component is housed in a coloured acrylic tube and encapsulated in an epoxy resin to assist in the overall sonic performance.
