You are a fantastic guy James. Not many people are willing to do what you're doing.
That being said, gotta love how everyone is gunning for the CK100s. something about costing 400 bucks, me thinks.. anywho, having the ck10s and loving them for their highs, I can only imagine that the ck100s will do that for me with mids. Someone long ago (may actually have been you, James) said that ATH, being a japanese brand, makes equipment to maximize enjoyment of japanese pop music, which of course, has a strong emphasis on high and mids. I personally love female vocals, so mids and highs are definitely the major point of interest for me. I think AwakenedBeing said that the mids of the ck100 are so smooth that only customs can compare, if this is true, then they probably do justify their cost.
I've also heard that the Cyclones are excellent bang for buck IEMs. haven't actually looked into them too much though.
Cheers, and thanks for the giveaway.
