I recently picked a used five channel amp (a Chiro C-500) so I can add rear
speakers to my existing 5 channel (a Chiro C-300 and C-200) setup. I have
just started experimenting but I was wondering what sort of setup other
people are using. Should I leave my front speakers on the C-200 and plug all
the others into the C-500 or perhaps use the C-300 for the fronts and the
C-500 for the sides and rears?

The issue would seem to depend on how manufacturers alter the power supplies
as they add more channels to the amps.

Thanks,
