Sure, but considering the large number of options available today, it is n=
early impossible to test all potential combinations of microphones and reco=
rders in an objective way by ear. So, it should help to have some objective=
measurements at well-defined conditions.=0D

I also believe that the ears alone are not always the best tool for evalua=
ting the equipment. The problem here is that one will need some kind of abs=
olute reference in order to compensate for the different microphone sensiti=
vities and recorder gain settings. A very experienced audio engineer might =
be able to do that quite well, but others may to end up with inaccurate res=
ults. =0D

I remember folks stating the Tascam HD-P2 had noisy preamps, which was obv=
iously based on judging using ears. This was one of the reasons why I start=
ed the Microphone Input Noise Comparison list 10 years ago...=0D
