Acccording to the fellow at Oade bros, he said the audio quality was as good as the SACD 222 and 555 players. Video was excellent but not as good as the 999ES. He also thought the 777ES was slightly more film-like but the difference was only visible in a side by side comparison. He couldn't understand why though; he thought the 555 had better shielding than the 777. He hadn't opened other units to see if this was true overall or a fluke for this one unit on the floor.
