Over the years I have bought many portable recorders to take room recordings of loud rock'n'roll bands. The usual problem I have is distortion making the recording unlistenable, and this seems to be caused by drums and cymbals.
I used this in a 20ft square (ish) room with hard (laminate) floor and minimal soudproofing to record a band consisting of acoustic drums, vocals (through P.A.), electric bass and electric guitar. We measured the sound pressure level at approx 90dB and the recorder was placed at floor level in the middle of the room, using the onboard mics. I used the limiter as the 'clip' light was frequently firing (the manual does however state it can handle loads of up to 125 dB). What we got was a nice clear recording with no distortion or clipping notable through the session. The recorder also maintained good clarity through the quieter moments.
At the time of writing, it's £150 cheaper than the Zoom H4N (borrowed in the past), and in my opinion much easier to use and with comparable sound quality (for my purposes).
