The more I think about this I'm inclined to believe the Duelund CAST is what its makers say it is . Personally I don't know of a Teflon capacitor that sounds like the Duelund. So if it is "plastic", how did they get it to be superbly organic and natural in character? The internal construction could be oat bran and toilet paper. Bottom line is they sound superb and serve as a supreme benchmark for other audio capacitors.
