I've just bought a new amp and speakers and want to copy my cd's to the PS3 in the best possible quality to take advantage of the amp/speaker capabilities. I ripped my cd's to the pc using windows media player using both the normal WMA setting and the WMA (lossless) settings to see which one sounded better and then copied them to the PS3 via a usb hd. However, PS3 will not play the WMA (lossless) files as it says 'unsupported data'. It will however play WAV lossless files. My question is: the file size for a WMA track is on average 2mb, but for WAV lossless files it is up 22mb yet playing the same track at each file size i can't really hear any difference - is this right? shouldn't a larger file size give better quality? How do other people copy CDs and using which format?
