A bit late to the game here and a Zu Dirty Weekend Supreme owner. Have these paired with a First Watt F8 and Modwright LS100 preamp. I listen to quite a bit of jazz and female jazz vocalists. I enjoy the sound characteristics they bring to the stage on this music. There has been mention of their trial period but let me also offer a vote of confidence for their customer service. I had numerous phone calls and emails with Sean and Garret both prior to and after the sale. They truly care and have always been very responsive to my questions. On top of it they are knowledgeable and fun guys. I am likely to move to a pair of Soul 6's in a few years.
