2 channel amp help

hello - my first post. while i am not completely ignorant in ht matters, i am not all knowing by a long shot so maybe one of you can help:


I am upgrading my current system to NAD 753 receiver and Asperion 5 series speakers (fronts, center and 2 surrounds). I also currently have installed outside Mirage oasis 5 omnisats. I know that I can just run the outside speakers through the "B" speaker selectors but would rather be able to listen to music on my patio while my 4 year old listens to cartoons in the living room


The NAD has multi-source output capability plus a second remote for this but not really sure what that means. I think it means that I can hook up a 2-channel amp through this and run the outdoor speakers into the amp - is this right and how does this work so I can accomplish what I want?


I have been looking at 2-channel amps and 2 I have found that look right are:

Speakercraft BB275

Niles SI-275


Are these any good (I have never heard of these brands) and would they do what I am asking?


Thanks
