Atmasphere, The right speaker was out of place because of several re-alignments due to impromptu visits from friends, auditioning Sky ICs vs my current King Cobras. I re-positioned the speakers last Sat night, using a tape measure from the seating position and side/back walls, and this was previous to the phase experiments. Imaging improved, and the late-night phase swaps tell me that when I had the speakers on the long wall earlier this year, they were hooked up out-of-phase. Having moved them months ago to the short wall to get better distance from the speakers, the hook up was phase-correct, so I was hearing a totally different (...and correct) soundstage compared to the previous setup.
Even with all these improvements, the image still hovers around the speakers, it's wide but there is not much depth to it. Future experiments will include both sound treatments *and equipment upgrades*...my timelines are measured in months and years, not days and weeks, gentlemen.
