Is Yamaha that much more superior than Denon as far as sound? I have been reading a lot of reviews its a mixed bag. I just want it too sound good..I have spent more time researching a AVS receiver then I did buying a new truck LOL I hooked up my old Onkyo 708 last night its only 1080 p it was activating a little funny on my 4K TV. I received my speakers yesterday I ordered the RP280 and RP450c front, when I open up the boxes they were RP 8000's and RP504c at the same cost $1095 for all, I was surprised. All the new features coming out, I almost want to wait for a receiver that has it all. The main reason why I started to look at the Denon x4500H because it has eARC and IMAX but my $3000 Tv doesn't have the eARC , not sure if it could be added in a firmware update its a LG C8 65 inch. Im still trying to decide on a Receiver that I will be happy with
