I had WP 8 for a couple years. Set up was CRITICAL, when they say every 1/2" counts they mean it. I also found that I needed "mellow" equipment and cables to counter the dynamic, forward presentation. They could be considered bright with bad silver cables and edgy gear. Once all of the appropriate ancillaries were in place I found that music was dynamic, detailed and fun to listen to. They had great imaging and pretty good depth. Music was nicely detached from the speakers. I never tried them with tubes, but I think they would have been really nice. I loved them for a couple years, but I came to the conclusion that they were too forward (un-natural) in the presentation. I switched to a Magico S5M1 which resolves a little more detail, sounds more neutral (to me) and are much easier to set up, but they don't have the dynamic slam of the WP8s even with the 10" woofers vs the 8".
