Initial impressions (much less detailed than Steve's, but hey):
Unit is small, light, and well-built. The screen is super-bright and easy to read. Everything on the unit generally works in a logical and simple way. Buttons have a stable and confidence-building feel. It's noticeably smaller and lighter than SD units, and about the same size as an R-44, though it feels much more rugged.
Bluetooth was the key selling point for me, and the controls did not disappoint. I set levels using it on an iPhone 6S and had no issues; you can also dial in levels more by using the 'PFL' menu and putting in the exact number of dB of amplification the channel should have. Ditto on the unit itself -- you can adjust levels with the knobs, but you an also enter the PFL menu and put it in more exactly, or do it on the main screen.
Steve is certainly correct that the level knobs are small. It felt more difficult to manually tweak than with an R-44, for example, because small movements can cause big changes and there aren't the "click" wheels that adjust the input sensitivity, which is just set at Mic for XLR connections and line for TRS (I bought some TRS extension cables Steve recommended so that my SBD feeds are line level.
It's also handy to be able to engage the limiter and actually know what it is doing. You can set the threshold at which it kicks in, which I had at the default -2dB and "soft knee." It kicked in a few times for me, because the set I was recording was a close-miked situation in a restaurant that isn't really set up for a full band rock show.
Everyone seems to have bitched about the headphone output. For me, I don't really care, as I just use the headphones to occasionally tell if something is in fact recording, not to have a great listening experience. But it is noisy. The preamps are not.
First recording is mixed down; I'll put up a link here when it's posted. Oh, and mine was non-Schoeps, so those wanting to hear other mics can get that chance...
