I really like these pipes, even after listening to them for well over a year. You need to make sure you get the stuffing, port tuning and positioning right, but after that they are really sweet. I find mine are warm, slightly forward, with a really natural acoustic sound that is very easy to listen to with most of my jazz and bluegrass material. They are broken up in the treble, at least on paper, but it has never bothered me. I do have some fibrous material around the whizzer cone that seems to take some edge off them, and I prefer them this way. I've also lined the inside of the basket legs and back of the magnet with felt with good results. I added a super tweeter, but I find it kind of irritating, so I don't usually run it.
