I do not own this product because the price suddenly skyrocketed (300 euros). For cons, I tried it at length with a Sennheiser Momentum on ear headphones. The sound of this audiophile player is excellent, very clear, very detailed and has nothing to do with the sound of a smartphone. In addition, this drive drive without helmets problem worthy of the name. Regarding the interface, it is very simple to use, because close to the ergonomics of an Android smartphone and the screen is very readable. The picture is more fine and contrasted. Having owned a iBasso DX90, a few months before his screen does not light up if the sound quality is comparable, the égonomie the AK100 II is beyond compare. I also tried the Fiio X5, and if the sound is also very good, the interface is confusing.
In conclusion, great sound, beautiful design (the object is beautiful and well done), excellent ergonomics compared to the competition, the price (almost 1100 euros end of April 2015) is high for this quality of sound. A look at Cowon Plenue 1 or M1 Calyx I ordered and I'm still waiting ... For information, the Calyx M1, is a bit bigger, cheaper, and with a sound so detailed but a bit more chaud.Si I could enjoy a AK100 II less than 800 euros (price in early March) I would have bought.
