Wonderfully explained Ian. In my relatively long experience in the A/V business there is a segment of audiophiles or any interest or hobby for that matter, that just takes some of this all too seriously spending too much of their time looking for the most minute differences in anything to justify their opinion. When it comes to speakers and audio in particular, this group always seems to be more wrapped up in the statistics and graphs forgetting why they bought the stuff in the first place, to enjoy the music and watch the movie at its best possible without having to mortgage the house to get it.
