ptaaty,

I second others' opinions here.

The first thing I would do is to run the MCACC, and then carefully compare the sound with the EQ mode set to ALL CH ADJUST, FRONT ALIGN, and EQ OFF (you can instantaneously change among these modes by pressing the EQ key on the remote). See which mode you like best (although the differences can be quite subtle if your room is well-tamed) and go from there...
