I should've listened. I really, really should have listened when I was first setting up my 2.3 TLs. People did try to tell me. Anywho, part of the lengthy shut down was so I could rotate the room 90 degrees and put my speakers on the long wall. They're now 5.75" off the back wall, 45" off the side walls, and just over 7.25' apart. The sound stage doesn't quite have the depth it did before, but the SDA effect is much stronger and the sound stage is just an eff-ton wider even though the speakers are just over a foot farther apart. Hard to tell how much of an effect not having a signal through any of my gear for about a year had on the overall sound though, so for now, they're spiked where they are and in a couple of months when I'm sure everything has had a chance to re-burn-in and settle, I'll revisit all this. But for now, I'm generally much happier with the overall sound and sound stage.
