You should really listen to the Harbeth's SH5's. I owned them for two years and they are the most musical speaker in their price range I have ever heard. Very easy to drive, sounds great with tubes & SS. They don't go real deep but they just sound right. I went from a $10,000 electrostatic to the Harbeth and both were enjoyable. It sounds like you are looking more for a floor standing speaker but I would seek out Harbeth's before you purchase.
PS - the reviews on harbeth's are outstanding.
