with the Sony ECM-MS 907 I take now to each concert our choir on MiniDisc (Sharp). The recordings have a small flaw in the bass range (can be with EQ slightly offset) but are for semi-professional purposes more than adequate. The setting option between 90/120 degrees is great. Important to note: There should be no micro extension cables are used, since it started with me to hum and noise on.
So I can do (structure plus tripod connection Micro / MD) super shots at an expenditure of scarce 5 minutes to even our great recording person (has a Yamaha AW1600 + 10 microphones) was surprised by the quality.
I'm very satisfied.
