First, no where can I find any documentation that states when bi-amping using only the 706 are you splitting the frequency. The 706 is simply sending the same signal to both outputs.

This is what it states in my 606 manual..... I can't imagine that the 706 would handle it any differently. Were it sending an identical feed.... it would not matter which receiver outputs you connected to which speaker inputs.

The FRONT L/R and SURR BACK L/R terminal posts
can be used with front speakers and surround back
speakers respectively, or bi-amped to provide separate
tweeter and woofer feeds for front speakers, providing
improved bass and treble performance.
• When bi-amping is used, the AV receiver is able to
drive up to 5.1 speakers in the main room.
• For bi-amping, the FRONT L/R terminal posts connect
to the front speakers’ tweeter terminals. And the
SURR BACK L/R terminal posts connect to the front
speakers’ woofer terminals.

In theory, just providing each driver with it's own power source could result in better sound. Since the front sound stage provides the vast majority of the surround sound experience... I don't think the loss of a few watts of power is going to be crippling to the rear surrounds.

I'm not saying that it will provide a huge difference in sound.... I once again state that the OP should try it both ways... and see which he personally prefers.
