Every component that does not sound good to you right away needs breaking in.
I think that the concept of break-in time is a post-sale customer relations tool used in the retail trade. The non-believers say that after a while your ears should adjust to the character of the new component and it will sound better. (I am an agnostic in these matters.)
I've never noticed a difference with cd players, amps, preamps or interconnects. Speakers, obviously, speaker cables too, but not a long time.
