Device to record & playback music ?

You might consider one of the stand-alone Tascam CD recorders (mine is a CD-RW700 but there are later models), which record on any CDR or CD-RW and produce quality discs indistinguishable from the original, IMHO. I also have an Otari MX-5050BII2 reel-to-reel deck too that produces outstanding recordings. The MD format (tiny discs, little space to write anything about the performance) has never appealed to me. Good luck, Dave
