This is a review based on the first impression, if something changes dramatically, I will again operate. I since 2 days use the converter now very intense and am really excited! As a player, I use either a Samsung Note II, a Galaxy Tab 10.1 touch or a Lenovo laptop. I've heard so far about a Beyerdynamic DT990Pro 250 Ohm, a Shure SE425CL and devil Inear. As a comparison to me, of course, the respective headphone outputs are available, but the divorce actually made from the outset, since they can not keep up in my opinion. Otherwise, there would also be no market for the Zusatzwandler- / amplifier. Since the Kunlun is now available only in Germany, I've kept me with a E07K Andes over water (a brilliant part, incidentally). My first impression is the haptics. This has nothing to do with China fragile devices that you might previously so held in his hand. The E-18 feels as if he were milled from one piece. All switches are stable and have low tolerances on. The service is quick and conclusive the first sounds are very excited. Da Sound perception is something very subjective, I will not indulge in the highest and lowest notes, because everyone has an idea. You can hear very loudly, but with activated bass enhancement it sounds too quiet as I had hoped. What bothers me really the lack of annoying influences from the power grid. The whole chain is battery operated UDN I like to think that you even noticing. Perhaps Voodoo? I hear progressive rock just as happy as film music. A beautiful voice also has some merit, Adele or Katie Melua are popular fodder. And acoustic guitars are very popular with me. MP3 I no longer hear really, but either WAVs or FLAC. But mostly I use WIMP to the music offline or heard as a stream, with Android not a problem. So, my conclusion: One should give the little helpers have a chance, he will most probably not be disappointed. A device, more functions: D / A converter with high quality components, Excelent headphone amplifier and charger for your smartphone. Taste and be surprised what you can use a smartphone or tablet yet. As perfect players for high-resolution music files ...
