Have you ever changed speakers to expereince a different "soundscape" or presentation??

Has anyone ever upgraded or changed speakers to experience a different "soundscape" or sonic presentation??

Whether right or wrong, I have always thought that different speakers CAN offer a different perspective on the music.played

Without tying this question to just sound staging and imaging,..... or planar, 'stat versus box speakers, has anyone been surprised or even stunned by listening to a familiar CD or LP, and believe it sounds different and more revealing than you ever have heard before?
