Title says it all.
I'm using a laptop, so I need an external USB Sound Card.
If you have other recommendations, please do state it here. I would highly appreciate it. Thanks!
Fiio E10 USB-DAC-headphone amplifier, $66, it's only 2 channel stereo, but should sound better then the Asus U3
If you need surround sound with a USB connect, then the X-Fi HD would do.
Chances are the E10 would offer better sound quality.
