Recommended Receiver for Helos 20s

Hello,

I have wired the two other rooms for MartinLogan Helos20 speakers, which are stereo speakers. Therefore, each speaker should have four connections to a receiver as I want stereo sound from each. I want to use a Sonos ZP90 with a separate receiver for each room. How would I set this up with a receiver to get stereo sound from each speaker? Do I need a multi-zone receiver?

Thanks,
Mike

Anyone?
