Yeah, I know what you're all thinking already, but..... More than a year ago I noted that there was a fairly obvious right speaker dominance---I even measured a 2 -3 db spl difference. The short story is that after checking all of the interconnects, speaker cables, removing and replugging-in everything, cleaning contacts, etc. I figured it must be room issues, and physically repositioned the speakers to pull the center image back to the left. This meant unevening the r/h speaker distance from my listening position both right/left and front/back. Not an optimal solution, I felt, but it seemed to compensate enough.
On an unrelated matter, I just had occasion to swap the USB cable (a standard A/B cable) running from my server to my dac. I don't recall where the original USB cable came from...something inexpensive and off the shelf. While I suspect the brand is probably not relevant, the new USB is a relatively modestly priced ($40) cable from a company called Supra. After swapping the cable, I sat down to listen and make sure that the music was still going to play and immediately noticed that the center image was now pulled about 4 feet to the left! Huh....that's strange, thought I, so I put the old cable back and image was back to centered. Needless to say I reinstalled the Supra cable and went through the process of repositioning my speakers to be equidistant from my listening position, the image was perfectly centered, and then remeasured the SPL levels...now equal from each speaker. Clearly the old USB cable was defective in some way....I have no idea what defect may have caused this particular problem but, as nothing else had changed in my system the obvious culprit was the USB cable. And, no, I'm not going to make any gratuitous claims about how sound quality has vastly improved, but at least the mystery of why the right speaker was louder is solved.
