I am taking the journey into separates. I just purchased some Marantz Amps. Marantz MM-9000 Marantz MA-700. I have a Marantz AV-550 Preamp. I will be upgrading to a newer model down the road. I plan on running the left front and right front channel with the MA-700. The MM-9000 will power the other channels. Will this affect sound quality? I wondering if the RF, LF and Center should all be receiving the same amount of power. The MA-700 is 200 watts and the MM-9000 is 150 watts. Thanks for your help.
