I am down significantly in midband in left ear. With digital or analog volume control, I raise left channel. Without, I shift position and speakers if I have to get stable center image.
I use Frank Sinatra All of Me and Ole' Black Magic from Platinum Collection to set levels. These two tracks have served me well for centering image, and Frank seems to sing Dead Center on both with pieces of the band behind him (esp on All of Me).
I also use noise generators to validate.
It might be useful for us if we can recommend songs with good production values and staging where a powerful male or female vocalist is dead center. In many songs (Even on Platinum Collection with Frank), singer is slightly left or right, not always dead center.
