I just received this little marvel, portable Amp/Dac from www.ibasso.com , one word for it is OMG, it has brought life to my HTC Incredible and my Ipod Touch, using my Klipsch Custom-3 ear buds, and it also is fantastic with bigger cans like my AKG K702'S, the D10 has just opened up everything in my music "especially my loseless files", depth, clarity, extension and bass are breathtaking, anyone who is serious about their music needs one of these, or something similar.
