So I'm looking for my first AVR and need some advice. I have speakers ready for a 5.1 set up. I may up to 7.1 in the future but it's not a priority. I intend to run my Nvidia Shield Pro through it for films and shows (not using anything live) as I use Plex server on the shield for a media centre. Many of my films are 4K so this functionality is essential although it seems most new ones handle that. I will also use the HDMI arc on my TV for this. I also would like multiple other HDMI ports as I intend to get some older game consoles (with a scart to HDMI converter). I'm not sure if I need ethernet on the AVR but it seems a good idea. How much can I expect to pay for this at the bottom end? And are there specific model recommendations you can make? Thank you in advance.
