Two pairs available. I recently purchased these pairs from an authorized AQ dealer which can be easily verified. Wind is an all Perfect Surface Silver cable in the new Element series replacing former cables such as Sky and Niagara. Very smooth and detailed with no brightness at all. A truly wonderful sound. See Robert Harley's review on AQ's website.. Take a look at my feedback as I work hard to please. U.S. Sales only. Shipping is $25 USPS per pair.
