I got to mess around with it for a few hours today. I tried various sets of instructions including a PM I received, the instructions from the link above, and instructions that were sent by the previous owner. Using the method from the PM the sound was kind of thin and a little bright. Using the method from the link above, the sound was too warm, muffled, and dull. Using the method from the instructions that were sent by the previous owner, the sound was just right.
Instead of setting a flat target curve, running auto EQ independently for the left and right channels, and making my musical curve afterwards, I set my target curve (which was my "musical curve") suggested in the instructions and ran auto EQ in stereo link. The auto EQ did a good job coming close to my target curve. The sound is rich, balanced, and pleasant sounding. It still has nice crispness and punch to it.
Overall, the Behringer may be the best $200 I have spent in audio (the Ack! I just bought is up there too). It's amazing how many features are packed into it.
