I bought an ElectronXout with the intention of giving it to a friend (I was lucky enough to get a Chimeric adapter, the top device in my photo of the adapters, when those were still being made), and I've briefly tested it in the meantime. For starters, the video quality is every bit as good as everyone says it is. I can't tell any difference between the Chimeric (which uses a custom analog-to-digital converter tuned to the Xbox's clock frequency) and the ElectronXout. I don't know why other manufacturers can't seem to figure out the analog-to-digital conversion aspect of Xbox HDMI adapters, but the maker of the Chimeric figured it out, and so has Electron Shepherd; you won't find another adapter that can output a video signal as clean as these two. As for the audio, if you've seen the "Special Instructions" section of this product's listing, you'll know that Electron Shepherd recommends enabling Dolby Surround, but disabling Dolby Digital and DTS, claiming that the latter two won't work. I tested Dolby Digital anyway, using ESPN NFL 2K5 and Forza Motorsport (I included a photo of the former), and shockingly, it worked. Maybe Electron Shepherd's recommendations are left over from an older version of the adapter (the early revisions genuinely did have audio issues), or maybe Dolby Digital doesn't work on other games, but in the case of the two games I tested, I can't tell a difference in the surround sound effects between the ElectronXout and the Chimeric (which always supported Dolby Digital and DTS) with Dolby Digital engaged. In summary, the ElectronXout is the only original Xbox HDMI adapter that's worth your money, and that will remain the case unless the Chimeric reenters production, or another manufacturer finally gets the hang of it.
