Well you claim technical specs are all that matters, right? That is your theory. Anyone or audiophile that thinks different is an audiophool, right? Technical specs are only a tool, doesn't tell the whole story, that is my theory. I use my ears to judge sound quality, that is all I need.
I just repositioned my speakers recently, just a a few more inches out from the wall and a slight change in toe in gave easy to hear improvement. Better soundstage width and depth, better tone balance and dynamics, for a more enjoyable listening experience, the only tools I used were my ears and a tape measure!
Moving your speakers for better FR is sensible and can be proven to be beneficial (or not as the case may be) by measuring. If you measured your room after moving your speakers you would see what had changed that is affecting the SQ - maybe boundary reinforcement issues had been helped, maybe you had corrected some small problems in the time domain, maybe some in the frequency domain too, maybe you had helped with reflection issues off the side walls etc etc. All of that can easily be measured in a few minutes and would show you why you could hear a difference.
More importantly, you may have made an improvement but it is not the best you can do in your room - again the measurements will help you optimise the system. They can show you why the imaging is now better for example and help you make small adjustments, or place room treatments, to make it even better still. Although you have mad audible improvements, you cannot be sure that you have achieved the best you can and it would take for ever to do this by ear - moving the speakers a little here and there, moving the sub, adding some absorption at a first reflection point, moving it a little etc etc.... all this takes minutes when you have some simple measuring gear.
The problem with Esh's approach is that he will happily drop say $300 on cables that can be proven to make no difference whatsoever to the SQ whereas if he spent the same on the OmniMic and a little time learning how to us it, he could make really significant changes to his SQ.
Measurements are not the only thing that matter - they are a tool designed to help improve SQ. And they are a better tool than your ears - you are wrong that "all you need is your ears". Ears are fabulous listening devices but poor measuring instruments. You cannot, for example, explore the issues of comb filtering, and solve them, by using your ears alone. This is why speaker manufacturers spend more time measuring when designing a speaker than they spend listening. Here's a good article - an interview with famous loudspeaker designer John Dunlavy - have a read - it's not very long and won’t take much of your time. Read why he says that no loudspeaker can possible sound better than it measures....
But at least you are on the right track - the room and speakers are what make the difference. Not 'audiofool' cables.
