Back to prospective buyers. I listen: classical music, especially opera, French and American rap singers ... What I owned: a cowon J3, a Colorfly CK4 +, a Ibasso DX100 and smartphones Samsung S, S2, S3, S4, S5, Note 4 My headphones: Sennheiser HD700, Sennheiser Momentum, Focal Spirit One, Bose Intra. After Cowon J3 not exciting, excellent Colorfly CK4 + which I still have but which is not practical (autonomy, slow, software) and a Ibasso DX100 (player exceeded in its features, and ultimately slow ... not terrible despite promises. Enough revealing puisqu'acheté 3rd hand and resold immediately and in my opinion he has not finished browsing of France), I was looking for another drive. My music is only compressed en Flac and needed a compatible device. Vaccinated by the experience of Ibasso DX100, I wanted a device not too expensive and even if I could put a little more to target the new X3, the X5 (which seems heavy), or Ibasso DX50 (fear of the brand ), I decided to take a small Fiio to start. Well I am very happy. The device is simple what suits me very well. It is very well finished for the price. There is no radio and I do not miss me because I have my laptop for that. I think the sound is very good with possible modifications by the equalizer. I'm no expert to detail as you can do some of the musicality Fiio X1. There has details, a good balance between the treble, mid and bass. It passes both from opera to American rap. I read it lacked spatiality and it is true that it is worse than the + Colorfly CK4 at this level. I would say it is below, but already it is cheaper and above all it is more convenient. I'm not ready to leave the Colorfly. The unit is lightweight and well protected in its cover "gum" catch dust! The buttons are all easily accessible. It is understood in two seconds how it works, no need for manual. One thing I taped it its power. Frankly, to 60 100, it sends bad enough and above all it allows a demanding driver helmet. For example, I no longer used my Sennheiser HD700 from the sale of the DX100 as the Colorfly was not up to scratch and we had to stick him an amp (Fiio) for the driver. There, no problem and HD700 headphones to good feast at home because otherwise we tripping over 3 meters of cable. Last thing, I have no problem with the wheel quite intuitive. Oh yes, also the battery life is very good for this almost audiophile player, much better than a smartphone that is forgotten in a pocket. I wonder if the X3 would have been better ...
