Hello, My father owns a Yamaha MD8 minidisc recorder and has a bunch of old recordings with various numbers of tracks. What would be the best way to import them into a computer with the lowest loss of quality? I would ideally like something that brings them in as files that can be converted to WAV/AIF as opposed to "re-recording" the files through another interface. Would one of the Sony USB based portable players be able to bring in a multi-track recording? Any other approach or gear folks can recommend would be much appreciated. Thanks! Owen
