Sigh .... has done for me (clearly better than my netbook's onboard), and also has done for a lot of others. Casey - there's no problems if it's not for you. Sell it and move on.
Not from a netbook - that static you're hearing is likely from the laptops onboard card. The DAC portion of the E7 is cleaning that signal - whereas the LOD/amp from the ipod is still using the ipod's DAC.
You won't be able to simply go laptop > headphone out > amp and expect to eliminate the static.
