I have used two different SONY digital voice records. Both set to 192kbs MP3 which they call SHQ in their settings. I've never had a problem with a loss of data. Crank the volume up all the way for playback. One was an ICD-700 and the other one is a PX-333. Either way you can't go wrong. Be warned, it is slow!
This also works with the NEC units. I suspect they could use a lower bit rate due to the fact that the NEC records at 600bps instead of 1500bps.
