Sorry for my bad english. These phones worh every penny they are very clear-high resolution, huge and holographic soundstage, strong bass, fantastic mids and really nice extended treble can't fault anything these are my favourite phones by far. I have the fischer amps rhapsody and the music maker showkwave iii but won't get much use after this purchase I think that the dc8 play in other league. They are more mid centric (4 mid drivers) than the others and the bass is quite strong but treble is very extended too.
Isolation is pretty good and the construction seems solid and nice.
I was going to buy the dz9 too but not for now I'm super happy with this purchase.
