Greetings,
Yes, I did similar to what you're proposing, using four channels of amplification on my two main speakers,only I have Magnepan 1.6QR's. I used Audioquest rca y adapters out of the preamp to split signal to the four amps. I don't know if Audioquest makes a balanced "y" connector/cable or not, but they're as good to try as any company. I understand they make more items than shown on website, so you may have to contact them to ask.
I found bi-amping to be a tremendous benefit. The sense of power and authority was well worth it. I'm using twin subs and still found a great benefit to biamping mains. The sound stage seemed "deeper" with it biamped, like the equipment had a better grip on the signal and reproduced it with more clarity/authority.
