Jeffrey,
ReplyDeleteThose are sweet looking boxes. Plan on raffling those off! :)
Just beautiful.
ReplyDeleteI just received mine from Jeffrey and it sounds as wonderful as it looks. In fact, it may be an even bigger upgrade than my Kahn phono. Now if I can just find a reasonably priced pair of 104D tennis balls to try! Thanks JJ.
