Both units are very impressive! However, you could spend MONTHS comparing the sound/video performance of the various connections and software options. Throw in something like an Oppo universal player, and a high-end HDTV with top-of-the-line upscaling, each with their own customizable options, and you end up with waaaay too many variables. Denon's Cat5/wireless G capability is interesting, but at this point, it doesn't even come close to the ease and convenience of a Squeezebox (or the forthcoming Squeezebox Duet). At least they recognize that streaming music/video will be the future. Personally, I'm more concerned with two-channel audio performance above all else, so I want to know if the AVP-A1HDCI really adds $5000 additional performance over the Denon 3808CI. I sure hope some Audiophile-grade reviews are forthcoming.
