I bought this new from Woo Audio about a year ago. It's by far the nicest headphone amp I've listened to, and it looks and feels the part. (If you've never seen a Woo product in person, they are incredibly solid and gorgeous creations.) It ships in the original boxes (one for each unit), with the original tubes (2x 300B, 2x 274B, 2x 6SN7GT). Asking $2,800 shipped within the US. Contact me for international shipping.
