I have been meaning to post here for some time to thank @Benjet for posting a heads up about this DAC. I grabbed one quite some time ago and managed to land it for AU$15. Hooked it up to my room system and was terribly underwhelmed but it works great on my Android phone (no extra power/hubs required) and it drives my HD650's surprisingly well. Super detailed it is not but it's perfect for Youtube/MP3 music and the like. It has a very smooth, easy to listen to character. I was quite pleased considering the small outlay.
