"Y" Connector: Can Split A Signal How Many Times?

.
Al, I'm a pretty smart guy, but I'm a math and science imbecile. So, let me explain my dilemma, and you can explain it to me in simpler terms.

I have a huge room (check my system page). I want to use smaller speakers in the rear of my home theater because they will be inobtrusive. I want to use three pair of speakers where there is only one pair of pre-outs. From what you know of the latest, newest pre-pros, do you think this is possible? I would keep the interconnects from the preamp to the amps to six feet or less. I would use interconnect cables costing about $100 each. Do you think this would work without much signal degradation?

thanks,

mitch

Pixel, I want each speaker to have its own discrete amplifier channel. A stereo amp powering six speakers doesn't appeal to me.
