I would just amp your front 3 XPA3, call it a day $600 done... if you really want to amp your surrounds, grab a upa500 for $350 to go with it... but at that point an xpa5 for $770 and a upa200 would make more sense... Go through emos catalog and pick what you think would work for you... you can buy a couple apa150's to run your surrounds too, but with emos sale they are a better choice... I would personally get hte xpa3 and let the avr handle the surrounds...
