After 17 years, I think I'm due for an AV receiver upgrade. I've been happy with the 5.1 performance of my trusty Nakamichi AV-10, but I want something new and fun. Here's what I'm looking for: Ample power to drive my B&W 603 S2s and Velodyne FSX-12 sub. I plan on running 5.1.2 by adding front up-firing ATMOS speakers, placed on top of my fronts Ability to add more speakers later Future proof support for movie audio codecs (Atmos, DTS:X) Good sounding 2-channel music (mostly streaming at this point) Auto calibration 4K HDR pass-through to my LG OLED B6 Works well with XBOX S for UHD Blu-Ray Nice to have: Chromecast support 1080p --> 4K upsampling Here is my consideration set at the moment. Sony STR-DN1080 Pioneer VSX LX303 Pioneer VSX LX503 Onkyo TX-NR787 Denon AVR-X3500H Yamaha RX-V685 Marantz SR5013 Suggestions?
