ASUS U7 USB Sound Card

The Package & Closer Examination »

Introduction


ASUS is one company that has for a while now been making quality PC-audio components for both gamers and audiophiles. Good sound quality can come in a variety of packages, and today, we will take a look at the self-powered U7 DAC/Amp solution from ASUS. Not a bulky, grid-powered solution, it makes sense for laptops and uncluttered desktops. The U7 is packed with features for home entertainment and has full 7.1 out and both coax and optical S/P-DIFF, which you don't see in a lot of external DAC/Amps. Apart from its many connectivity options, the U7 also features a headphone amplifier that can be used with medium demanding headphones.
