Maybe one of the head-fi sponsors could get help us out. If they're able to get a big purchase on some CD3k's, then maybe they could make a one-time deal with head-fiers to increase the number they're buying, while adding the CD3k to their inventory as well.
That is.. if Sony would sell only CD3k's to anyone. I seem to remember one of the retailers/head-fi sponsors mentioning something about how Sony would only sell headphones if the retailer was willing to sell the full range of Sony headphones or something like that, and advertised the Sony line in color (whatever that means). Does anybody else remember seeing this too? If so, this whole thread may be meaningless, unless we're interested in buying the rest of the sony line as well.
Edit: Maybe you guys might be able to try this with some other brand of headphones, like Sennheiser, Beyerdynamic, Grado, Shure, Etymotic, or whatever.
