Curiosity got the best of me and I wanted to compare the DX-200 with the AK380. I actually prefer the DX-200's interface. This particular unit has the Lurker Firmware installed so you don't have to side load android apps. I purchased it here: https://www.head-fi.org/threads/ibasso-dx200-amp1-amp3.878034/#post-14215158 and have put probably an hour on it since then. Asking 775 shipped and paypal'd in ConUS. Thanks for looking.
