Received my 820 yesterday and relegated my OPPO 203 as the backup/SACD player. Played around a few hours and fine tuned it to my liking and I have to say that it's what it's cracked up to be. Outstanding PQ! I always left the OPPO on Auto in the settings because the HDR options all gave me weird PQ. With the 820 the slider and HDR optimizer are a godsend. I tried both the SDR2020 and HDR2020 and prefer the HDR2020.
