Hi, I sold my Pioneer VSX924 which was a little bit dull and boring, and want to buy a new AV receiver for my TV room. My 5.2 Setup (100% movies and games, no music): L-C-R DIYSoundgroup Fusion 6 Rear Cambridge Audio Minx Min11 Sub Dual sealed 4cu. ft. Dayton Ultimax (amplified with Behringer NU3000DSP) Also need ATMOS, because I will install 2 DIYSG Volt 6 for that matter. I live in Chile, so I don't have that many choices for an AV receiver. I can get these: 1-. Yamaha V583 for USD$649 2-. Sony STR DN1080 for USD$931 3-. Onkyo NR676 for USD$830 I can't listen nor try these, as all three should be imported first. So, from the reviews I've read, the Sony is the best of the three, but it's also a 40% more expensive, and might not be a 40% better. Build quality is important, as I will probably wont have any warranty. So, from your experience which one should I purchase? Any experience with any of these? Please only consider sound quality, dynamism and excitement, and not other characteristics as HDR, 4K, upscaling, casting, apps, etc. as are not that important to me at the moment. Looking forward to your help.
