Probably everything that is to be said about the subject. If only one could post sound samples of both.

I wonder if this is the case. Clearly I like the idea of 40khz.
Regardless of the limits of human hearing, the human voice rarely even reaches over 8kHz (some harmonics go higher but really not much up there). The harmonics that do reach that high tend to be rather annoying anyways. You still want a mic that covers the range of human hearing to get a complete "soundscape" or maybe record a freaky sorprano but your dialog mic is getting it's workout in the 100 to 10khz range.
ye3p that why i nailed another commercial yesterday with my chiniz friend another 300000 production value to go i bet i will finish it till the end of the month( 2comertials and 3 promos , by the way i am not sure that the rest of 7 chapters for a serial i starting in the end of the month which previously where recorded with gefell 210/schoepses i will not make with these 2 ,. as they don't pay me so well and brought me another asshole to boom ( i fired the booman from the previous session .
