When you have time, will you update your post #3 to include...
it's in the works
I will have add in some model comparisons as soon as I have a chance, but in general the "tiers" are the same as last year's models, with the slight change being that the 1611 is 7.1 vs the 591 being 5.1:
591 = entry-level 5.1 unit with analog>hdmi video conversion but no scaling/processing
1611 = identical to 591 but adds two more amps that can be assigned (surr.back, front height, bi-amp, or zone 2)
791/1911 = adds a handful of small features and video processing, but still no GUI
891/2311 = adds better video processing, GUI with volume/status overlay, etc.
From last year to this year, the biggest additions are HDMI 1.4 / 3D / ARC support, with the trade-off being reduced legacy connection options. Basic amp / sound quality should be the same.
I'm looking for a Denon model that will covert HDMI 1080 24p to HDMI 1080 60P
only the higher-end ABT-2010/2015 equipped models can do a 1080p framerate conversion (i.e. 89x/23xx and up).
