Thanks, I will try to do it.
I've tried this EQ preset. It indeed makes the sound of HE-400 close to LCD-2's. The music is gentler and smoother sounding, the treble is not harsh. However there is also some loss of air/openness and impact. Depending on the kind of music I would choose version with or without the EQ preset. For electronic I prefer the sound to stay unchanged.
Thanks for the comparisons!
