I might be ripping a lot of MP3s soon for my new Hard-drive player (HD5) but I was wondering whether in general, it matters at all as to what program you use to rip MP3s. How much do Encoders effect music quality at the same bitrates of MP3? Do HD players take on the batton of quality or do they all decode it to another standard? I usually use CDex 1.5 which uses a LAME encoder (though they may be a new Lame Encoder out since then). Also, if one wishes to use the latest version encoder (eg LAME 3.97), can they install the codec and automatically have the older programs ripping with the new version codec?
