All I can tell you is that for me personally, it takes 2 to 3 songs before I 'adjust' to my home speakers after listening to others for an extended period.

Of course, it's all within the mind. Obviously the speaker does not change during that time so you can say "Bah, it's all in your head." and either way, 3 seconds or three songs, you'd be right. \:\)
