I was planning on buying the "top-of-the-line" MZ-NH1 and found out that it was discontinued. I found the MZRH10 to be very interesting so I decided to compare specs of the two models. I am planning on buying an HD-MD for field recording so I want to make sure I get a model witht he best recording sound possible. There are a few minor differences between the two models but nothing that would/should change the recording quality. The only difference that I found to be interesting was that the specs for the MZ-NH1 mic input said: Mic: stereo mini-jack (minimum input level 0.25 mV).......the MZRH10 mic input said: Mic: stereo mini-jack (minimum input level 0.13 mV) This might be a silly question but would the difference between 0.25 mV and 0.13 mV mean anything to the recording quality?
