Summary: If you are a male, this is the best recorder. Extensive personal testing verifies the size and quality of the speaker reproduces a lower tone (male) voice better than others. This unit has stereo capability. Useless. Microphones are 1 inch apart. Quality is better, but stereo spearatioon is nil. On longest player setting (LP) sound is poor. On standard play mode (SP) sound is excellent. Can upload several hours' speaking into computer in about a minute.
