I have been usign NetMD and later a owned a first gen Hi-MD... 600D I believe, so I'm planning of purchase a new Hi-MD, the RH1 seems like the best option, but I want to know if there is something better for me. Almost my entire collection of music is in MP3, followed by AAC files... I don´t want a player that has to convert the file to Atrac and I want the best possible quality since I hace an Audiotechnica closed headphones. So, RH1 or what? PD. I'm not much into recordings.
