Very good alternative to onboard sound

Since the performance of my onboard soundcard for me was no longer sufficient enough and my Technics RP-DJ 1210 were not challenged had for me an affordable solution ago. Due to the many good reviews and recommendations I have decided for this product.
First, I want to say that I am not an audio expert. Nevertheless, I use for years good headphones and listen to a lot of music expresses. A relatively trained ear, I would like therefore to write me.

For device and service yourself:

-The Supply was done by Fiio extremely quickly. The packaging was acceptable and the converter was without prejudice to me. Top!
-The Processing leaves no wish unfulfilled. Top!
-Lieferumfang's Fine, you do not need more in my opinion.

The sound:

The E10K is definitely the better alternative to onboard solution. I am totally impressed by the features and the whole thing for a really good price. The installation is very simple and hassle of drivers do not need to be installed.
After some tests with my current favorite songs (Techno, Minimal, House, Ambient, EDM, IDM, Death Metal), I can only report positive:

The bass is stronger, cleaner and without distortion (gain set to high). When I turn the bass boost, the earcups paddles properly with -Wahnsinn! In the song "Must Attack" by Extrawelt here very strong club feeling comes up, other songs call almost selbiges forth. Nevertheless, the sound remains undistorted, because only the deep bass frequencies. The highs and mids are clear. Mir is the Bass Boost personally too much, but it's not bad to have something.

I am blown away! For the price you get a lot of power and with correspondingly good headphones has you much joy with Fiio E10K. Clear recommendation. (Etc. installed sound card) For people who do not feel like screws and great installations, you should view this transducer times :)
