Powering Revel M20's.

I need an integrated amp for these speakers. Since I just bought them, I don't have a ton to spend on an amplifier. I was thinking either the Musical Fidelity A300 or the A3? I'd prefer the A3 because it's cheaper, but I know I'll need the power of the A300. Also, I thought about the Audio Refinement. I've had this one, but I'm having trouble finding another one right now. What about older Creek separates? Any good? Thanks for your suggestions.
