Do I have enough power?

I think Bdgregory is right, the answer is....maybe. I was driving my Mani-2's with a Cary CAD-120S Mkii which was putting out a rated 120 per into 8ohms and it sounded wonderful, perhaps a little "loose" in the low end for the bass heavy Mani's, but still very, very good. I wish there was a yes or no answer here, but depending on your listening tastes and room the lower output of the Rogue may or may not do it for you. If you are not able to audition the Cronus, you might consider finding a used unit which can, if it doesn't send you, be flipped costing you pretty much only freight. I'm now running mine with Rouge M-180's and I'm nothing but smiles. The Mani's will gladly and hungrily take as much power as you can give them, but I find they very much return the favor.

Rossbernstein-
Yeah, I figured out my misread shortly after my post. What is it exactly about the Mani's that you find yourself not sold on? Just curious. At times I have issues with them, other times they're just perfect. That's very likely no different than any other speaker I might have purchased. They were by far the most challenging speaker I've owned to figure out how to drive, but that's probably because I wasn't hitting them with an amp of sufficent power. I did find however that it's easy to find retailers who will tell you that the amp they are selling will match wonderfully with the Mani's. They were, well...selling.
