Hm, interesting. Not sure. But it doesn't read that way
in the owner's manual PDF ( available on M.F. site ).
The diagram of the back side appears to have a
typical mains 3 prong male, too.
From the manual:
"The X-DAC is powered directly from mains, and will also
happily supply power for the X-RAYV8 CD player and
X- PLORAV8 tuner components."
I will verify this with my dealer next week.
