As a previous RH1, RH10 (current), RH910, NH900 owner, I would go with the Sony PCM-D50. I recorded Marc Cohn a few weeks back and was just blown away by the clarity and depth from my croakie mount SP-BMC-12 omnis into the mic input of the PCM-D50. Of course, being able to go 24bit helps too. But, the ease of operation and visual display, battery life, etc made it the easy choice for upgrading from my Hi-MDs. Of course going Line input has yielded excellent results as well. Check it out. Good luck!
