I usually hold back with effusive praise and am generally not so easily impressed. The Fiio X1 I bought on recommendation and a short trial hearing. Add to that a couple of Koss Porta Pro Stereo Headphones are on the go. The device sounds with those of headphones already really good, but I could stand in comparison with my i-Pad Air 2 found no significantly better sound. Something better, something finer perhaps but there is no in between worlds. All well and good, a more or less meaningful toys more, whatever. After a few days ichs simply daring and my old Beyerdynamic DT 990 Edition rausgeholt with 250 Ohm and connected with little expectation. Ok, what came next was a revelation. I've never heard of this headset such fineness of music. Really unbelievable how this inconspicuous device dissolves the music and outputs three-dimensional. And even at a much more efficient that need headphones! However, you can go to full volume easily, without even begin to become distorted and therefore I can with the Fiio really my Beyerdynamic fuel! The audible differences to my Denon AVR-X2000 and the i-Pad 2 Air are gigantic, as if you use a different headset. I hear details in the music that had not previously perceived. The violin in Lindsey Sterling Crystallize suddenly playing nuances that I do not hear out of the normal system, not even in the car with the Bang and Olufsen sound system, amazing! So who has a collection of high-quality MP3 and something good would like to do, which was to test the device times. Recommended, however, is a good headset, because as I said, with a cheap headset, it is not necessarily not as big a revelation and the distance to the 08/15 player or iPhone.
