Asus sounds off with its Xonar U7 MkII external sound card
 

The folks at the Asus labs had a sound idea. The company revised its Xonar U7 7.1 USB sound card and labeled it the Xonar U7 MkII, in true audiophile fashion. The box delivers playback at a 192kHz sampling rate with 24-bit resolution, and this time around it's powered by a C-Media 6632AX chip. A built-in headphone amplifier helps the unit drive high-end cans without breaking a sweat.
