All Denon flagship AVRs have the 7.1 analog inputs, but for non flag ship models in the 3000 and 4000 series, they stopped about 10 years ago so the last one that has them would be the AVR-4311CI. and the AVR-3808, possible even the AVR-2808CI.
For some reason, Marantz hangs on to this up to now. To me that is not a positive but a negative one because they are indirectly forcing the majority (I bet 99%) of the customers to pay for something they will never use. They should have followed suit at least 3 years ago if not sooner.
Imo, keeping them on flagship models are fine and fair because those who can afford flagship AVRs may not mind pay a few dollars more for a feature they may need occasionally, or they actually believe analogs are always better so they may not mind using those and give up some bass management and/or auto REQ etc.
