If you subscribe to the idea of speaker break in, then I submit that the sound quality must be in a state of continuous decline as speaker break in suggests wear and as the speakers age the sound must therefore degrade at a continuous rate.

Still believe in speaker break in?

Listen and enjoy the new speakers \:\)
