Sorry I assumed you were talking about breaking in the reciever. I believe most amps, recievers, what have you, sound a little bright at first. I think the sound becomes a little smoother with time and use.

To me this is a must with speakers! When I build a new pair of speakers, I let them run for about 50 hrs before really listening to them.
