"...is way bigger than your little headphone amp" I'm not sure why this is a problem as I have my little HP amp on top of my Players. That's good then. Anyways I came here to find out if the Sony Player I have would play 24bit files from the USB port and if not would that other model I brought up in my first post do it...it appears not. Also, if I was getting the full SQ from a SACD...strike two. Regarding the USB port it's too bad WD Play doesn't make a reader for Audio files like it does for video. If I came across anything I will let you know, for now nothing, unfortunately..
