I'm not familiar with the receivers from Rotel. But can tell you that most receivers I've ever heard are NOT as strong as comparable powered separates, even from Rotel themsleves! Some receivers have done much much better in regards to current deliver, dynamics, impact etc, from my findings, however - so you might just have to try yourself. If you don't like, return or sell it.
Usually, receivers offer a somewhat softented dynamic, I've found, and amp section's powersupplies therein have to drive lots of components, in the receiver, not just the speakers. The results are usually not as strong of a current delivery and effeciency delivered to the speakers, all things being equal.
But, traditionally, the rotell stuff has been pretty dynamic. So you might give it a shot. Good luck
