In the audio world there aren't many low cost - high quality film caps. Some of the ones commonly available are a little edgy sounding, add sssh, and sing along with the music due to loose windings, voids or poor quality films etc.. When we were sourcing parts for the LD91 project we had a difficult time finding reasonably priced large value caps for the WE connection. At 2004 Electronica Asia I met a rep from the 5th largest cap manufacturer in Asia. A view of the factory showed new production machinery from Italy and Germany in a spotlessly clean environment. The company was sympathethic to our audio cap issues. Samples were made with extra tight winding, no voids and thick coated aluminum film imported from Germany. The results were much worth the effort so we ordered the range below. They are wound tight, very low inductance, no voids and with imported materials as described. Leadouts are soldered copper, solid core for the dry types and for most of the oil types. Spec'd at 5% but on average much closer than that. Sound can be subjectively described as smooth and easy.

Consider these to be the equal to supreme or premium series film caps.
