"Breathing" of the air

Hi folks, I would like to ask you the following. With some audiophile set ups I'm able to hear what I call "breathing" of the air, as if the air surrounding voices and instruments is a living entity, as if one is capable of hearing individual air molecules, if you know what I mean. Are you familiar with this phenomenon? Is this quality inherent to some amplifiers or speakers? Can you mention set ups that have these characteristics?
