If you need multizone capability and an AVR that can supply a large amount of power, I would recommend any of the Harman/Kardon amps, from the AVR 335 upward. They are 7.1 channel units, but you can also run them in 5.1 mode and use the two rear amplifiers to power a separate zone independently. They even come with a second remote control to power the second zone. They also have a mic setup, as does pretty much any high-end receiver.
