I heard the opinion that some speakers keep improving even after a few thousands of playing hours. I cannot comment on that as I always bought used speakers.
To return to cables, they do need some time to settle. Maybe in many cases it cannot be heard by an average ear. Just because a person is audiophile doesn't necessarily mean that he/she has a good hearing. Sometimes I read posts here that clearly indicate that unless the poster is not telling the truth, he/she cannot hear a thing. Some of my non-audiophile friends have better hearing than I, at least in some respects. The strongest point of my hearing is perception of space and rhythm.
