I currently have a Denon AVR-3808CI (2007 model I believe). 2007 was 6 yrs ago. My dad just bought a Denon AVR-X3000. Not much has changed. Its pretty much the same AVR plus / minus a few bells & whistles. Mine has more power, a phono input (not that I have a record player lol)... his has less power, no phono input (he does have a record player), but it has HDMI 1.4a, upscaling to 4k and 3D (kind of pretty irrelevant) and not much else.
So, question is... what killer new features are coming out "soon"?
* 4K is a complete waste of money at this point... no 4K sources, limited TV selection, etc. 4K will never be broadcast due to bandwidth limitations. Most channels are still 1080i (on DTV) with some of the PPV channels and VOD being 1080p.
* 3D is dead
* 5.1 is "good enough" for the majority of people. Most content is still 5.1 max. Yeah, some audiophiles want 7.1, 11.3, 92.27, etc. I said the MAJORITY of people
. Besides, even with your 92.27 setup, you'll still be playing 5.1 content
* Networking support on AVRs is pretty meh... can already do DNLA on all my other devices. Ok, my 3808CI web interface is a joke, but I've used it a total of 2 or 3 times in 6 yrs.
Other than that... AVRs seem to be in the same ball park as smart phones... what else ya gonna do with 'em?
