Hi group, my most recent reply was rejected from the group for some reason, so I'm trying again without the full email chain.
The DM-720 only has Voice guidance (recorded voice) like the DM-520 and DM-620. The main difference is that you can now set the time and date independently via Voice Guidance. The DM series including the 720 only goes up to 48K 16 bit. Comparing the in-built microphones recording quality of the DM-520 and the DM-720, the 720 is much improved - it uses the central mic and I would be comfortable using good DM-720 voice recordings as the basis for higher-quality productions, tutorials etc, but for me, the DM-520 quality doesn't really make the grade. I haven't used a DM 620 but my sense is the audio capture is nicer again on the DM 720, based on Neal's review of the DM-620, but I can't be certain of that. For higher sampling rates and higher bit depth recordings, the Olympus LS-P2 is the newest pocket-sized machine, a kind of replacement for the Olympus LS-7. The LS-p2 is about twice the price of the DM-720 and I haven't been able to justify buying one. For my purposes, I predominantly needed a machine that would reliably capture voice recordings easily. If you want a recorder to quickly and reliably capture voice notes, discussions etc, there is a big advantage in using the DM-720 or the DM series machines. That is, when you press the record button, recording immediately starts, even if you are not in a recorder folder before you press record. In that case, recordings are placed in Folder A In comparison, with the LS machines, pressing record puts the unit in record-pause so you can monitor and prepare for the recording. Pressing record a second time starts the recording. Also, for the LS-14 - and probably for the LS-P2 - record doesn't always initiate if you aren't already in the correct folder beforehand. Hope these explanations help.
