How was this measured? IMO both values are excellent. I own very good gear
with a SNR of 90 dB and I own crappy gear with a SNR of > 100 dB. I can't

Why do sound supermarket microphones with better specifications than
Neumann, Brauner, Schoeps, Telefunken etc. less good than those branded
Don't believe the hype, trust your ears. I've drawn graphs by hand for one
of the companies I worked. Is this fraud or common practise?
I've got a crappy Hifi amp (I like it anyway) the specifications show
SNR by IHF-Kurzsschluß, A-Netzwerk 103 dB, but by DIN/50 mW 89 dB/ 69dB.
Specifications often include estimations, statistics. Do you think that
e.g. two transistors from the same batch have got the same values? And
will they have the same values after you heat them in the oven?
IIRC it was Fons who some times ago has written that "most devices perform
better at 48 KHz". This is what I experienced too, while I indeed own two
devices that did sound better at 96 KHz on my computer.
