This is a spectrogram of clock ticking. MKH80, MKH405 and gefell M300. Recorded with Nagra LB. Both MKHs have higher noisefloor at both extremes of the spectrum. Though MKH80 is perhaps a bell shape EQ while MKH405 is a shelf?

To my ears gefell is the noisiest of the three. MKH80 the cleanest (by a lot). While it doen't suppose to record ultrasonic freqs there is quite a lot of relatively healthy signal up to at least 35khz. Perhaps not flat though.

MKH80 and 60 have similar noise characteristics at the top, though there is no signal above 20khz. At least I've never seen anything on spectrogram, unlike on 80 a 405.
