I use Samsung Galaxy SIII (Wolfson WM1811 Audio Hub) + Vsonic GR04 Pro Flagship (50 ohm).
The thing is, I listen quite often to old jazz records which are quiet so I have to amplify the volume quite heavily. I don't equalize frequencies, but Preamp is set to max and sometimes I have to use another application (Volume+) which amplifies the sound a little bit more.
And as might be expected, at high volumes the sound is distorted, I guess it is called clipping, I'm not so familiar with english words in this field. For example when there is a saxophone playing high notes it is quite bad. I have it loud but not extremely loud, I guess everyone would describe it differently :).
So I'm thinking about buying FiiO E6, the only thing which bothers me is if I didn't went over the limit of headphones themselves, then the quality of amplification wouldn't matter...
Any opinions? Thanks.
