Awesome IEMs you got there, James444...Atrio being the bass monster it is, and both Audio Technica models, one of them the demanding flagship with remarkable clarity and impressive highs and mids, so appraised by ljokerl and others...I do notice though that there are several AT models in your list...any special reasons for selecting the CK100 and the CKM70 for the giveaway? It's just that I really like the company, being the proud owner of a CKM-50 and a CK7 (pretty much low-tier, but the company's prices do not allow me to have more than that), and was wondering if you're giving them just because you don't use them as much as the others...
