A technical site that is reviewing DACs
I ran across this site a month or two ago when I was looking for information on USB DACs. Not having a background in digital audio, I've found it useful to learn about some of the things that I need to look out for when trying to find the appropriate hardware for my setup.
He's started to review some of the more inexpensive DACs you see on the shelves at the office stores and Walmart, etc. like the Turtle Beach Micro II. The site itself is located at Northwest Audio & Video Guy.
