The PCU is a Polypropylene film and Copper foil winding. It is extremely warm and rich, yet clean and detailed. As with all AudioCaps the PCU has Gold plated OFHC leads. The high purity of these leads makes for a very soft and delicate construction. Great care should be taken in order to avoid excessive bending or loading of the leads. Tolerance is listed as 10%.
