I'm curious, since I've never seen one of these units up close, how does the changer work when you set it to random and have a mixture of Redbook CDs and hybrid CDs in the tray? Does it play only Redbook? Do you have to manually push a button and tell the player you want to listen to a certain track in SACD? Do you have to stop the player to switch between Redbook and SACD? I'm the type that likes to put in five discs, hit random and walk away for a few hours. I wouldn't want a player that would require me to keep running over to it to manually switch between SACD and Redbook. Thanks in advance for your help.
