It seems to me you moved your speakers, heard a difference which is normal, but gave up before you had dialed the placement in properly. When you moved them, did you do it incrementally as I suggested, listening after each small adjustment for the position in which the music snapped into place? Or, did you rather move them a foot at once and then listen? When you moved them farther apart, did you then incrementally adjust the toe-in? I don't believe you did. Otherwise, your report here would be different. I believe you made a fairly large adjustment. Listened and didn't like it, and then moved them to their original position, which is not the optimum placement. My apologies if I have this scenario wrong.
Of course moving them is going to result in a different sound. That's entirely the point. You are complaining about your sound. You want to improve it. I know with absolute certainty that part of the problem you have with the sound is due to the present placement of your loudspeakers. I also know it seems easier to throw money at power conditioning and power cords, but in the end, after you have spent all the money, your system will still not sound its best.
Your desire to jump into spending money is a common thing, but you're buying a fancy carriage before you know your horse.
