Greetings,

I do not know if this is the right section to post this question, nevertheless we can move it later if needed.

I will start by listing the setup.

Speakers
LSi-15 (FL/FR)
LSi-C (C)
Wharfedale Diamond 10.7 (SR/SL)

Onkyo TX-NR5010 (AVR)
NAD C275BEE (PA)
NAD C275BEE (PA)

Basically the question revolves around providing maximum power to the LSi-15!
  1. Would I benefit from vertically bi-amping the NADs and allow each PA to drive 1 LSi15? Onkyo is rated @ 220w @ 6 ohms and it will be driving my LSiC, OR is it better to drive the LSi-15's on 1 NAD, and the LSi-C on 1 NAD?
  2. Onkyo has a Digital Network Crossover, would this benefit in my setup?

    What would be the effect of the passive xover in this case?

The idea is to benefit as much as I can from the setup, high volumes are nice but sound clarity is the goal.

Hope to receive as much guidance as I can.
