I want to buy a small portable sound recorder. I've looked at many but though they mention the recording format (mp3, WAV etc) they never state whether it has the full 96dB signal to noise ratio you'd expect of 16 bit recording. I want one that you can plug an external pre-amp into (not a mike) so it must take line level. Can anyone recommend a recorder which has a line input and which gives at least 96dB signal to noise ratio? Thanks
