If you've heard those speakers and you like 'em, mazel tov. I do suggest you listen to as many speakers as possible before deciding, though.
Receivers don't "lack bass". Bass comes from the subwoofer.
As for subs, since your heart is set on that one, then I guess telling you that for a few bucks more, Hsu, SVS, or Velodyne can offer better bang for the buck would be a waste of time.
What, exactly, attracts you to that particular receiver? Does it have a specific feature you need that others lack? A 5.1 receiver might offer better value..
