Admittedly, so far I had never criticized the volume of my AsusXonar sound card, since I mostly use 32ohm headphones. But the voltage difference one notices not only the volume but also the frequency response. Dynamics and precision vary significantly for the better. For example, comes to more pressure in the low frequency cellar. What is missing, however, is a headphone port for 6.3 jacks. It is precisely the high impedance headphones have such. While this can be solved with an adapter, it would have been nice anyway.
Let's take a closer one to the sound:
Among all the headphones (so about 13 pieces) I have not decided on the most expensive model, but went to a neutral sonic signature as possible. And provides the devil Aureol Real.
Starting with a fine jazz deposit from the album "One is the other" by Billy Hart Quartet. Even minute after the first half is immediately apparent the Omni gives the Aureol Real a lot of room abundance, dynamics and natural warmth. In direct comparison to a mobile source of Aureol Real sounds cool, slightly less powerful in the lower frequencies. But now it is almost as if the sound effect of broadband and plastic. When it comes to deep bass you do not work with dirty tricks. The draft is enormous but it is resupplied no unnecessary, "super-infrasound like bass boost". Due to the slight heat that turns the Omni, everything looks very natural and not analytically cool.
It continues with film music by Elliot Goldenthal's "Titus". The choir at the beginning of Victorius Titus sounds powerful, and non-staining. Subsequent inserts timpani not destroy the beautiful sound with a gimmicky monstrosity, but remain airy and serene. Everything sounds beautifully transparent and although is not thrown here with Tieftonanteilen around, the bombast of the orchestra is available only through the enormous dynamic boost to the Omni to the devil Aureol Real fed. This becomes even clearer in the title "Revenge Weel". The horns sounded pitch-black in the lower elevations and show enormous physicality without adding fat even once in the bass.
Now for Anna Ternheim's album "The Night Visitor". Ternhem's voice is gentle and easy. This is however not at the Omni or the devil, but to Ternheim's slightly cool voice. The challenge here is not sound throaty or covered to let that voice and masters the team from Creative and devil properly. The plucking of guitar strings is presented beautifully clear, but not overdrawn. More details in the background are wonderful perceptible. The stereo width and the virtual stage are impeccable.
A bit more Beat: Villain of CocoRosie builds on a pleasantly punchy beat, the superimposed anything and thus provides a further transparent sound. The quite high singing singers could act quite annoying, but they do not. As with Anna Ternheim the two siblings are CocoRosie tender and silky displayed.
And because I'm so bad on orchestral music, the conclusion again something modern: "Master of Shadows" by Two Steps From Hell. An epic, bombastic orchestra with synthesizer and large, mixed choir. Everything plays loud, emotional and at the same time. The synthetically-rhythmic bass playing with light pressure and is every second of the remaining Tieftonanteilen the other instruments differentiable - so it should be! Again, a powerful platform and momentum is built up and only when the male choir comes with the action, it could be critical because it follows the women's choir, which can like sound distorted somewhat weak or easy times on mobile sources, in combination with an unfavorable headphones , But even here there are no unpleasant surprises recorded.
Installation:
The compatibility is without flaws. The driver ran smoothly under Windows 7 and now even Windows 8.1. One gets the installation not having: Connected and ready.
Compared to Asus Xonar DG:
The Xonar DG is an excellent for their price range, internal sound card with built-in headphone amplifier. But in direct comparison it sound sounds somewhat less dynamic and does not point to this authentic warmth, like the Omni-sound card that makes everything a little piece appear larger and more plastic.
Conclusion:
I do not know how it actually behaves with 600 ohm headphones, but the difference is noted already even at 32-ohm headphones. The sound is vivid, dynamic and above all, authentic. Points, the card continues with two RCA outputs for a stereo amplifier or monitor speakers and one optical digital output on the rear panel. Also available: a small remote control.
Pro:
+ Great sound
+ Connectivity
+ Easy installation
+ Remote control incl.
Cons:
- No 6.3 jack available
