has some great descriptions for doing a setup like you want using a standard
receiver.

You will need impedance matching volume controls like:

for each channel.

The connecting block is unnecessary, just run all the wires back to the amp,
or combine them with a wire nut.  the block is just for a cleaner look.

I still think my $100 solution was just as easy, but I suppose it doesn't
give independent volume controls for each room that this more expensive
option would allow.
