From what I've read, the treble on the H-100 isn't anywhere near as harsh as the DN1000.
Have you heard the UE900? That's the closest thing I can think of in terms of midrange/treble, since they both use the TWFK and I wouldn't be surprised if they were using the same filter even.
Did you mean the treble on the DN1000 isn't anywhere near as harsh as the H-100? The treble of the H-100 is piercing and its hard to get a good fit on those, being huge.
I heard the H-100 has a similar signature as the TF10s according to Clieos
I haven't heard the H-100, but I would say the DN1k is less harsh than the GR07 BE, which I'm assuming is less harsh than the H-100?
