One is 40 inches and the other is 48 inches in length. These are outstanding cables for the price. Here is an excerpt from a Stereo Times review ( full review at link below )
"Getting to the meat of the matter, the strong suit of the GA-0’s is their ultra-smooth, grainless and relaxed presentation. To my ears, their tonal balance is nearly neutral. They offer deep bass slam, weight, and articulation when called for, and make midrange instruments like brass and woodwinds sound as naturally smooth and sweet as the actual acoustic instruments can sound. My hunch is that this smoothness is a trait of the pure-gold connection from connector to connector. The cryogenically treated gold-alloy wire makes a glorious highway for signal transfer."
