yeah, when i heard them, i felt they weren't as aggressive or as strong in the midbass, a reason i might want to keep LCD-2 as well. didnt have a chance to really test out the sub-bass.
the TH-900 hit about as hard as the denons i think, maybe a little more slam though just cause the bass seems to have more tautness and a bit more speed and control. more, i'm not sure, but definitely not less.
i would love to say that they didn't have as strong of a sub-bass, but a bit more mid-bass to finally balance it out nicely, but then i'd just be making stuff up and/or guessing
