I echo homedads response. My denon 2805 is pretty darn accurate. Like him, I don't turn on the RoomEQ stuff. In regards to delay(distance) and dB levels, it does a very good job. I usually check the levels with the RS meter from the same location, to fine tune a few things. I also change the mains to Small, and usually bump up my center channel dB's a little higher than my mains.
Did you put the mic in the primary listening location, about ear height, and have nothing else running in the room, you need it quiet..?
