i have the Onkyo 343 and I'm contemplating getting into the UHD Blu Ray world with a Panasonic player. Problem is though is I'm not sure whether my Amp will pass through HDR. There's conflicting information out there whether it will or not so wondering if anyone has one and has tried it. I know it passes through 4K as its used daily for Sky Q with no problem but obviously it's not passing through HDR. Presently have a normal HD Fire TV stick, Sky Q and a Panasonic BR player. Contemplating an upgrade to the new 373 and selling the 343 before buying the UHD player but would prefer to know if l actually need the upgrade before shelling out more £££. Any ideas how I can test without a UHD player on my set-up?
