Per soundandvision.com: "There's another feature called High Clarity Sound that's directly acces- sible via a dedicated button on the remote. Push this once and some of the player's video circuits that might interfere with audio get shut down, though the disc directory remains displayed onscreen (assuming you're using a screen). Push it a second time and it turns off the screen output as well." https://www.soundandvision.com/content/panasonic-dp-ub9000-ultra-hd-blu-ray-player-review-page-2Hi, Can someone explain what the high clarity sound mode is and should it be turned on? Thanks in advance.
