Hi Matt,
I met up with John Garcia today. He told me you scored some SDAs. If you've got any questions, just PM me. Optimal setup is 6 -8' apart, 6 - 12" from the wall, no toe in and at least 3' from either sidewall for the full SDA effect. That's optimal, I've got my rig in a catty corner arrangment and they still are wonderful 2 channel and HT speakers. I'm not sure about your Emo, better check with them about the common ground issue. They aren't that hard to drive, but they likey the current. If the LPA 1 doesn't work, be patient and score a nice 2 channel amp. I've run mine on Carver TFMs, Luxman and Adcom with great results.
If you get them setup correctly, they will be extremely hard to upgrade out of...wide, tall, deep, detailed and make studio musicians sound live. You probably know this already.
Congrats.
