From these posts, am I to understand that you have and keep your own speakers in DPoLS? When you talk of DPoLS changing due to changes in delivered sound, it accords with my own experience that the "best speaker position" can literally change from one track to another on the same album, which I mention to illustrate not only the extent of the problem but the impracticality of a complete/total solution, as well. If this phenomenon can be explained by phase vs. frequency  in the room, then even understanding the problems does not offer a lasting (or convenient) solution for the Musical omnivore. Lately I find that I am wasting my time worrying about speaker placement before my system is completely warmed up, and the electronic cobwebs are blown out. Paul S

So how do you reposition the speakers in a properly conducted A/B test? Do you have a methodology you can share? Do you change the distances from the walls, between the speakers, toe-in/out? Which parameter you start from? Cheers, Jarek
