Atmosphere headphone cables were engineered prior to Foundation and is based on our Tricon geometry. As for the Foundation headphone cables, it’s a pure 6-9’s silver conductor in an air dielectric, 100% handmade geometry and terminated by hand in my Southern California factory and conditioned on our massive Tesla Coil. It has the same house sound as the rest of the Foundation Series, but in the case of the Sennheiser variant, is specifically voiced by me on Sennheiser headphones. Both are great but I’d likely go for the Foundation at this point.
