Going by my experience with the previous gen of Images, you will probably be fine. However, I have no idea just how different the newer gen is. But I say probably when I consider the typical listening volume, typical distance, and typical room.
When you say "push", see, that could mean lots of things.
Therefore, I vote for getting a receiver that at least has preouts. You probably won't need them, but they could be nice to have. Even just getting a cheap used pro amp to run the mains or something can relieve a bit of the load on the amp, if you ever wanted to, but I'm guessing you'll be fine as is. But, just a dumb guess. The preouts at a small premium will give you peace of mind, just in case, I think.
