Marantz Receiver (SR7008) 125W/9ch, Rotel 1090 and 2 pairs of floorstanding B&W's

I am bi-amping both the pairs of speakers. I am thinking of bi-amping LF circuits of both speakers with the Rotel (200w/ch) and then bi-amping the HF circuits of both speakers with the Receiver's built-in output of upto 125W/ch.

Speakers are CDM 9NT and 804 Matrix Series 1
I couldn't find the information online much but I figured that the LF circuit would be more power hungry so should be powered by the Rotel, while the HF circuits should be powered by the receiver.

Thoughts?
