eMax,
The stated specs for your receiver rate the amp section at 110wpc with only two channels driven. I also noticed that the whole component weighs only 26lbs. I don't know, but I'm sensing that there isn't much of a power supply there. My two channel stand alone amp weighs around 40lbs.
Whatever you get, I'd stick with speakers that have a pretty stable impedance curve and are pretty efficient. I'd stay away from B&Ws. They really like power to sound their best.
