I just wanted to let you know that I received my WA6 yesterday in good order. Though I know it is not broken in yet and it will only get better; after a couple hours of warm-up time it sounds totally awesome. So good in fact that I listened to many favorite recordings long into the night. And the fit and finish is first rate at any price, for the money I am VERY impressed to say the least. - Email noted by RD.
