Ok I sent back my NW-HD1 player as I am sick with Sonic Stage and with no MP3 playback and am NOT paying £15 for an upgrade! The music was jumpy on some tracks and sometimes a track would get corrupted!! same thing like on my NW-MS90D! Since CD is digital audio and when converting it compresses it to NON-digital audio am I right in believing that a CD walkman and Minidisc walkman give superior sound over MP3/Atrac3? If so am I just better off with a Minidisc walkman? Thanks.
