No need to be snarky. I'm not claiming superiority over you, so your audiophile manhood is safe.
What I am saying is that yes, I can hear when one speaker is not symmetrical to the other by several inches. And if think you can't, you're not listening intently enough.
So don't signal me out. I bet most anyone you would care to ask in this forum would say the same thing. But hey, it's your system, so carry on............
