It looks like the DG/DX/D1 all have the same sound processor and therefore sound almost the same. The DG has an up to 150ohm headphone amp instead of the fancy dolby enhancements that the DX/D1 have and a slightly higher quality analog output. For $30 though, go for it. They'll all sound phenomenal.
Yeah…I think I’m going to go with the DG model. I have some sweet Harmon Kardon speakers and sub woofer I found in my mom’s house that were hooked up to her barely living Dell desktop. I tested the speakers by playing Pink Floyd’s “Dark Side of the Moon” album and it sounded sublime.
