Hi there I currently own a pair of Mirage 890i's from the mid 90's I really enjoy the sound from them (Using a Pioneer Elite TSX-53 to drive them). I'm thinking of upgrading to the above speakers soon . I have 2 Questions 1. Is it an upgrade or more of a sideways move? 2. Of the 2 speakers which in your opinion is a better choice?(If anyone has suggestions in the same price range I'd be interested to hear them,thanks in advance for your help.
