Still running good for you? I have a Denon purchased in 2011 when I got my plasma, so it's out of date and no 4k/HDR etc. Currently looking at their AVR-S740H as it has all the basics for audio codecs and HDR. Also on sale right now at a decent discount so probably going to pull the trigger.I've got a Denon AVR-S710W. Its an older receiver but it has everything I need. Handles 4K video, HDR 10 and all HD audio formats including Dolby atmos.
