Selling my Epsilon R1 Grado build. The drivers are from Elleven Acoustica, hybrid cups are Metal with Mahogany inner sleeves. The headband, gimbals, rod blocks and leather headband are from a vintage Grado Rs1. The cable is made from Mogami 2534 Neglex Quad Cable and *is terminated in a 1/8" mini plug*. Ear cushions are genuine Grado L-cush that are about a month old. The drivers alone cost $119GBP ($160+ USD) plus shipping!
*I recently changed the termination to a 1/8" standard jack for convenience. It is no longer balanced termination.
The drivers are press fit in the sleeves adding only a thin strip of electrical tape for a tighter fit. Mahogany sleeves are in place with by placing blu-tak at the bottom, so they are easily detached from the aluminum cups. Travel case NOT included.
