My "new" 4K UHD Blu-ray player also plays SACD's so I bought a couple of discs to try it out. Not impressive, the sound seems "muddy" or "muffled"
Maybe I've got the wrong combination for playing SACD.
Yamaha RX-A2A receiver, Sony UBP-X700 /M 4k UHD player. DefTech Studio Monitor 65 speakers. SVS SB2000 subwoofers (2).
HDMI 2.1 cables, 48Gbps connects the Sony player to the Yamaha AVR. 3 feet long, can't go shorter unless I stack components on each other.
