Thanks for this. One more thing: the MZR37 says it doesn't have a mic sensitivity switch, but otherwise looks like a nice, rugged machine for doing some basic interviews, and readily available on the s/h market. The MZ-R55 does have mic sensitivity, but doesn't appear to be so durable or geared up for easy recording operation (I could be wrong!). From what I've read the audio technica mic is OK with a suitable cable for MD recording, but is this sensitivity thing likely to be a big deal with either the AD or the Sony mics? Thanks in advance.
