Sorry for your (and that buyer's) losses. :(
At least you gained a new ally, the im02s.
These guys are badass. The bass is phenomenal, just like the ck10s. The mids are still impressive, despite the lack of a liquid "colored" mid-range.
The highs, while not as sharp or fast as the ck10s, are definitely better than the ck10s as the silibance can be controlled, the highs are also thicker, as is the midrange..
This is my identical to my impression. I want to cautious because I only just got them but they don't seem to have that AT midrange coloration.
