I wonder, what is the link between preparing those files (which

should not involve anything except editing and maybe getting the

levels equal, i.e. no hardware involved at all), and that discovery ?
Anyway, this is still an 'easy' test, it doesn't stretch the

hardware to any limits at all.
The difference between the Behringer and the Micstasy is not

about 'audio quality' in the sense of frequency response,

distortion, etc. It would take really bad engineering to get

those so bad that it would matter.
It is all about technical qualities that *do* matter if things

get a bit more difficult: hum levels, noise levels, the ability

to change the mic gain while recording without any risk and by

a defined amount, resistance to RF and mains interference, being

able to supply stable phantom power on all inputs, etc. etc.
Try recording a contemporary music concert on location, with

percussion ranging from barely audible scratches to a bing bang,

and voices switching between whispering and screaming in a matter

of seconds. This sort of thing even takes a Micstasy or an Aphex

1778A to its limits. Your B. will fail miserably.
