I'm selling my RWAK100 that I bought from a seller here very recently. Here's the thread from the previous owner: http://www.head-fi.org/t/698366/iriver-astell-kern-ak100-dap-modified-by-red-wine-audio-rwak100-2x64gb-msdc-2-cases
It's in the same state as I had gotten it in and works perfectly. It has several, shallow scratches on the back and the volume protector (which is removable, I believe - I haven't removed it) has color rubbed off, but otherwise, it looks nice. Comes with two brown cases (one case is great, one is a bit roughed up), the original AK box, including the micro USB cable, and two 64GB SanDisk microSD cards.
I'm selling because I like my iPhone 5 + DAC/amp more, overall.
The price includes paypal fees + shipping and is firm. I may accept trades, but don't count on it.
Will post pics in a couple of hours.
