After some testing for me the appropriate converter

You have to be a little careful with the ratings in such subjective things as "sound". I am not a type for any superlatives and advertising messages. Dewegen I judge the device rather sober and in terms of its usefulness.
Processing I find very appealing. Since all sitting really perfect. The gaps are spotless. One may want to touch the device. The aluminum and a solid workmanship make real head turner.
I've heard the Explorer at home against the DacMagic and the V-DAC. With fixed-out on a Denon AH-D 7000 and Corda headphone amplifier. What I particularly liked the Explorer of the "musical" sound. I do not hear the converter itself actually. I want to listen to music yes. Often the instrument very sharp, analytical and hard in digital devices. That was for me the DacMagic. Therefore he fell for me out of the race. The V-Dac liked better, but he had not this river and he disappeared not so nice behind the music. For all the devices I mean an improvement for 24h to hear. As long as I fed each transducer with music.
Well, what I'm saying. Everyone has their own Präverenzen. That's why I find reviews (points) and so absurd in magazines. I hope that my writings one or the other to move to give the Explorer a chance. I think he has a deserved.
One more thing, which is a real shame. You can operate the computer only him. It is a pure USB device. It is a pity. But certainly wanted to avoid kanibalisieren their own devices.
The packaging is nice. A bit like Apple. The description is good and the decor really simple (tested with Win7).
