“Every pair of Diana V2 headphones is machined, finished and assembled by hand in the New York facilities of Abyss Headphones. When you order your pair from Abyss you can also select the termination of your cable. Options are 6.3 mm or 3.5 mm unbalanced, 4 Pin XLR, 4.4 mm balanced or 2.5 mm balanced. One set of Diana V2 headphones retails for 2,995$ US.

For everyone who wants to tickle even more performance out of their Diana V2, Abyss offers an upgrade cable by JPS Labs for the V2, called The Superconductor HP. Retail prices of the Superconductor HP begin at 1,400 USD. We will also find out what improvements it brings over the stock cable later.”
