Hi, IMO the author of the article has 6 transistor radio ears. I agree that many things do not seem to matter, but equally many do. My personal experience has been that coupling capacitors do have a significant sonic signature and will alter the sound. Absolute polarity does as well. My system allows for easy swapping polarity (most don't). The polarity is sometimes difficult to determine with many recordings. With well done stereo recordings that have a singer in the center it will often show up as to whether the singer is in front or behind a line drawn between the speakers. Correct phasing will normally put the singer in front and supporting musicians slightly to the rear or in line with the speakers. This does require that the system is set up well and has flat response in that frequency range. Unfortunately again not all recording studios are consistent in the phase and worse some try to make it zero. In that case you lose a lot of the ambience and depth of the original presentation. With ear phones the issue is not really significant as few (except special ones that cover the whole ear and have multiple drivers) can distinguish the difference.
