So far looks very good. Internal microphones are... well standard electret of average quality (nothing spectacular). Stereo separation at 120 deg is good, however i prefer true 3D recording with my own "magic device" which luckily can be plugged as external mic. There is some noise at max microphone gain, but that is expected.
Some very good features available. As 48V phantom supply for plugging in professional mics via XLR. Automatic recording above selected threshold - nice when you're somewhere on remote area without your DAW nearby and need to sample a lot of stuff (i.e drums). There are 3 limiters and compressors that come very handy here too. At 16/44.1 quality is good. Didn't tried XLR line inputs yet and the 24 bit / 94 kHz mode. Will do these tests later today - regarding the real noise floor of this unit.
