The standard approach in professional audio world would be to 
use signal distribution amplifier.

Try to get a set of isolation amplifier that has 
isolated outputs (each output has output transformer 
to do the isolation). If such thing is nto found, 
then just use a distribution amplifier and have each 
output connected to each amplifier through audio isolation
transformer. This guarantees full isolation.
