[QUOTE="Bennett Prescott, post: 40531, member: 4"] Awesome post, Arthur, I completely agree. I take all my measurements with an older Superlux ECM-999 and some Rational RTA-420s. When I need high confidence above 8kHz I now have an [URL="http://www.rationalacoustics.com/store/microphones/isemcon-emx-7150.html"]iSEMcon[/URL] that is really fantastic value for money. As Arthur said, normally I am setting levels up there by ear anyway, so absolute value is not important. I own a few high end mics, including a 4007, but they are not in my road kit. I have the 4007 to check my other mics against, and for when a client wants certifiable measurements. Having the 4007 is worth it for the latter case alone, it has paid for itself many times over. P.S. The error between my cheapest mic and my most expensive mic is basically zero to 4kHz. At 16kHz it is less than 3dB. You pay for a few things things in expensive mics, in order of relevance:[LIST=1] [*]Response above 12kHz [*]Flat response on axis (cheap mics tend to have their flat response off axis, and a 3dB buildup on axis. The bigger the capsule the lower the frequency that this begins) [*]High max SPL (cheap mics start to hit their distortion figures around 115dB) [*]Low noise floor (cheap mics may have a 40+dB noise floor) [*]Weather handling (reliable measurements in high and low humidity and temp) [*]Long term stability (hundreds of years for <1dB change in response) [/LIST] [/QUOTE]
