just as an FYI for those who wants to know...
the Fubar III is a combination of the Fubar II USB DAC and the Cute Battery II headamp
both of which i happen to own and have been very happy with for about 2 years now. especially after shoving in 2107 and 627 opamps in them
EDIT: also forgot to mention...that the cute beyond has always been regarded as a better amp than the Cute Battery II. which is most likely why Skylab commented that the amp in the Fubar III isnt as good as the Beyond.
n in case anyone is wondering, the Cute Battery II (aka Fubar III's headamp) drives my DT990 250ohm easily.
