Rogue Audio Cronus Magnum II or Pharaoh Integrated

I have a pair of Revel F206 speakers and am wanting to upgrade the power. I am sold on Rogue Audio, but I wanted to know which of these amps would be the best option. The Cronus Magnum II is rated at 100 WPC and the Pharaoh is rated at 185 WPC. I guess my main question is whether or not the Cronus Magnum II can really power these speakers, or would I need more power?

In your other thread I mentioned the specs on the Revel F206's, particularly the impedance curve. Speaker sensitivity is 88dB, nominal impedance is 8 ohms.

The curve shows the speaker is driven well below 8 ohms throughout most of the frequency range. Plus an 88dB sensitivity and a recommended amp power of 50 to 200 watts nominal. A 100 wpc tube amp will not supply the power to drive these speakers to their full potential, basically they won't sound very dynamic.
Although, I love the sound of the Cronus Magnum, it needs a more tube-friendly speaker.

The Pharaoh is a killer amp; a tube stage and a Class D amp section. It would should sound good with just about any speaker.

Bbroyles23,
As far as the Cronus Magnum driving your Revel's, I suggest you call Mark at Rogue and ask his opinion regarding how the amp will perform. Tell him about the impedance curve;
on paper that's what says these speakers aren't a good match.

The Cronus Magnum is such a great sounding tube amp.
