What I don't like about the xenyx I've seen so far:
various compromises:
The fx I saw was 40khz sample
but the DAW (DA converter)
is 48. Not that I think you could hear it
if you upsample to 256, but possibly
if you downsample again to 128.
You still need to have unused faders
down for best performance.
Some features are deleted in the non-FX
units besides the FX.
Some units have a 9 beq (barely enough)
and higher up models don't seem to.
The individual mid contour is fixed frequency.
The treble freq. seems to be a compromise
more for cymbals than anything else.
