Jmos, what is your verdict?
My verdict...is that I think it's a fantastic box.
Without rehashing too much of what other reviews have said about it...
-I think the powering situation is great. The RC batteries last a long time and are a great solution over li-ion or lots of AA's.
-I really like the XLR-1/4" locking combo jacks.
-The mic pre's are very good. The adjustment knobs are tiny, but that's a good thing for once you have them set. Sound is excellent out-of-the-box, and even better with the busman mods. Seems there are some cheap parts in there (not unlike many other of the recorders out now).
-Headphone out is powerful enough, but is noisy. At a loud concert this wouldn't be a problem at all, but is a little disconcerting when recording quiet sounds. Recordings are clean, and this becomes evident once you listen to them some other way.
-Now that they've released a new firmware, you can have full metering in color on the side panel, which is really handy if you use it in a portabrace like I've been doing. There's also a PFL peak LED which lets you know if your mic pre is clipping.
Every person & or report I've found that's done any audio testing on it has come back and said the results are really, really impressive. It's got some quirks, but every new recorder that's come out does. It's a great package, is very well thought out, and is well worth the $$$ IMO. I would definitely choose this over a Marantz 660/670/671.
Hope that helps.
