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.

There are probably not a lot of people posting here that have
personal experience with all of these amps.

The local shop carried Chiro until Kinergetics went out of business,
but I never heard the stuff! IIRC, there was a receiver and a
preamp-processor.

Seems to me that Zippy used to talk about Chiro products occasionally.

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?

These products all apear to be the same output stage module packaged
in varying numbers per box.

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

If the amps have the same continuous power rating per channel with
all channels driven, then the power supply has been scaled up
proportionally to the number of channels. Given the nature of
multichannel music this means that at worst the 5 channel amp is as
capable in the real world as the 2 channel amp. It also means that
at best, the 5 channel amp is more capable than the 2 channel amp,
but marginally so.

In fact any audio power amp that passes a continuous sine wave test
has a power supply that is vastly overbuilt when it comes to
handling music.

In short, I don't see any advantage to reconfiguring, presuming that
of the amps are all in equally good operating condition. Any audible
gain would be less valuable than the work it takes to recable. The
biggest advantage I see to the 5 channel amp is that is would appear
to be smaller than the 2 channel and 3 channel taken together. The
biggest disadvantage I see to the 5 channel amp is that it is
heavier and bulkier than than either the 2 channel or the 3 channel
model.

I guess the OP could sell the excess amp, but considering how little
he'd get, it might be more fun to add channels to his setup.

Bridging could be an option.
