Looking forward to your thoughts on those speakers.

What I have done in the past to compare speakers is to (obviously) use the exact same material and listening/speaker positions as well as SPL. I like to write down my thoughts while listening, then swap out the speakers, recalibrate and wait an hour or so or even a day in between to keep the sound fresh each time. Once you are done look at your notes and see if there are similarities and blatant items you didn't like.
