Room modes (standing waves) can do weird things. You might get different results by moving the source.

I read this somewhere: "Monaural is like listening to the music through a hole in the wall. Stereo is like listening through two holes in the wall." Even monaural sources sound different when played through the two speakers of a stereo system, because more room modes are excited strongly.
