It all depends on your speakers since this is the critical interface. Are you keeping the Revel's? If so, assess their amplification demands and then choose from a shortlist of amps that will mate correctly with your speakers. If not, put off the amp decision until you are into speakers that you like and are going to live with for a while. Not knowing answers to these questions nor your budget you might consider the Modwright KWA100SE or the KWA150 (or the SE version of the 150 which is moving up another price point). Good luck!
