Not really. Both have very up-front lower mids, and the treble on the HE-400 could be seen as more in your face and distracting enough to take away from its bass presence as well. In fact lots of people say the LCD2 sounds so bassy because its treble is lowered.
I'm just comparing raw bass levels here, I had the perfect opportunity to compare both side by side for days. Both have around the same amount of bass output and linearity, but the fact that the LCD2 has a slightly tighter bass makes its bass less present quantitive wise most of the time.
I also have white driver HE-400 instead of transparent driver, if that means anything.
