I am setting up a new 5.2.4 home theater. I have a Marantz AV8805 and a Yamaha MXA5200 in the mail. I have Monitor Audio Silvers all around and 4 of Monitor's CP in-ceiling speakers for the Atmos channels. I will have two extra channels on the Yamaha amp so I plan to Bi-amp the mains. My question is should I use Yamaha's bridge feature to do this or should I use the Marantz processor option to send two separate signals for the mains each to a separate input on the Amp? Would love your thoughts. Thanks.
