I set the B&W pretty much flat and give the 10Khz 1-2 steps higher, if the song has been well recorded
It all depends on the song and recording. I personally don't think there is a default Equalizer setting that sounds good on ALL songs, but a Flat curve is good 80% of the time. I am always tweaking this and the Bass/Treble settings from song to song if I have the volume cranked up.
Because of this I have the Tone Settings programmed into a shortcut button (1-7).
I have programmed No 3 short cut button for this
