The impression is terrific today. I hear only mobile, go home, always Lossless from the iPhone. Between my ALAC files and my T 5 p was previously the DAC of the iPhone is the weakest link, which is now compensated for the A 200 p. The sound is extremely good, much less distortions (I assume virtually no true in music that I hear often for months or years and can compare from the habit quite well) dissolved, everything sounds more transparent and better, whether House or opera or rock or Jazz (if the recordings are good), basses are as full, but no emphasis on the bass, the mids clear and breezy, unless the headphones participates. Any type of equalizer can be forgotten in my experience, because as good as the music comes straight from well-established CDs, they must be improved through postprocessing.
The integration with iOS devices is excellent (volume is synchronized with the A 200 p 135 volume levels offers vs. 16 gradations when iPhone). The control dial for volume is cool, just pretty slick, so it offers little resistance to rotate with your fingers dry.
Since Beyerdynamic not proscriptive the user, you can turn off the volume limit. I need only at certain serious music (classical, romantic, modern operas), which has such a great dynamic that the slightest Piani with volume limit is too low Rock, Pop, Electronica, Dance, House are with volume limitation also on T 5 p always loud enough.
These are well spent 300 euros, especially if you, like me, in practice only mobile listens to music.
