I own a Denon 3803, it has no auto equalizer either, but I do not experience the brightness problem you describe with my 340's. To find your reflection points along a wall, you just need an assistant and a mirror. Simply sit down in your listening sweet spot, and have the assistant move the mirror along the wall in your direction at the tweeter's height until you see the speaker closet to that wall. Mark that area with tape. Now keep moving the mirror until you see the opposite speaker. Mark that area. If you have a center channel, you can mark the wall where you see it in the mirror as well. Repeat the procedure for the opposite wall. If those areas you marked are bare, or there's glass or some other relflective surface there, temporarily hang something like a large towel or some other obsorbing soft material on the walls. See what that does to your treble.
