I really think NuForce's Icon Mobile is a top bargain. I'd like to start a thread full of reviews for it. If you don't have one, it's $80 and a fantastic deal. I'll start with my review:

Of course, if you have any questions please let me know. One thing I forgot to mention in my review is the jitter issue with overclocked computers. Basically, there can be annoying jitter with overclocked computers in DAC mode. This only happens when you are using both a combination of BIOS overclocking with software overclocking in addition to dynamic clock speed control. For example, Intel Core i CPUs have turbo mode. When this enables, you can hear jitter.
