I've helped a handful of folks w sound for short film, and, especially w/ VO, I'm asked about "that noise in the background." most recently this case was presented to me, after I had made recommendations on recording (do whatever you can to minimize the background noise of NYC, monitor your input) and there was really a lot of noise on the recording, which was done on an h4n, even on the mic channels that had no mic plugged in. the built in mic recordings were, to my ears, barely useable.
as I think I detailed earlier in this thread, when my 1st gen edirol R09 was stolen, I upgraded to the Sony D50, and would make the same choice again. I do not use XLRs in most recordings where I deploy the D50 (field and "studio) - some studio situations where an XLR or four are needed, usually Richard Kamerman brings his Sound Devices, or I'm w/our friend Charlie, who also has a Sound Devices (722 I think).
The D50, for my uses (field/room recording or direct line from mixer) as been exceptional in terms of quality and reliability. If I'm going to cash out on a mic setup that requires XLR, I'm going to cash out on a Sound Devices rig too.
