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.
