I haven't heard yet a nice sounding setup with Revels in general.
While I've never owned any Revels (for probably reason of not being "my type of speaker"), but have heard them in various hi-end shops and into at least several shows and never Revel auditioning impressed me. Perhaps there's no amp that could drive them to open. Everything was as-if the sound was preserved in each of the speaker boxes and never went out.
I think you should aim for something that will give you closer to 1kw per channel.
