Hi Pneumonic,i can honestly recommend anyone using a redgum six channel to bi amp, this is a cheaper way of getting there, but by no means a inferior method.
Redgum surround amps , under the skin, are like two channel amps, doubled up. there is nothing missing sound wise. Short wire runs, quality throughout.
connections on the back to each and every amp section . you can tri amp also if needed . and the air it produces is in another world.
a few years back a six channel was not outdone by a krell intergrated in a review, and this was running single channel hookup. I myself, tried it up against a theta two channel, it beat the daylights out of the Theta. The redgum is without a doubt, a audiophile grade surround amp. find one secondhand just buy it!! I will never sell mine.
