A note on break in on these speakers from Music Direct:
A word on burn-in: normally we don't talk about burn-in on speakers, but The ONE is so unique we felt it necessary to comment. Out of the box, The ONE requires about 150Hrs of play time at moderate levels to come into its own. Although exceptionally good out of the box, during the burn-in time the bass curve flattens out, the midrange opens up and the high frequencies (already good) sweeten up and extend considerably.
