I listen to 2-channel music materials in the DPL II Music mode most of the time, with the "center width" set a bit broader than the default (meaning, the center channel level set a bit lower than default). Especially, when I listen to the FM classical station, I always use the DPL II. When I listen to CD's (mostly classical), I sometimes use the 2.1 Stereo mode, depending on the nature of the particular recording. But my "default" is the DPL II now.
