Hi,
My setup is 5.1 ch.
Denon 4308Ci use as a pre-amplifier.
Sunfire Amp is Bi-Wiring to LSIs.

I thought in the future:
I.- Setup 5.1 channel:
Sunfire Bi Amplified (front and center).
Use the terminals of the speakers of the Denon 4308Ci (Surround Speaker A and Surround Speaker B) for Bi Wiring LSif/x.
Bi Wiring LSif/x: Using a Woofer in B and Tweeter in A, connecting the speakers.
Denon 4308Ci configuration A + B Surround Speaker management
Is that correct?

II.- Setup 7.1 channel:
Sunfire Bi Amplified (front and center)
Use the speaker terminals of Denon 4308Ci(Speaker Surround A and Surround Back Speaker ) for LSif/x:
Surround Speaker and Surround Back Speaker
Is that correct?

I would like to hear your opinion
