Krell Showcase because of the Class A discrete analog circuits. It will be smoother than the Anthem, which is usually op amps and switching power supply. With the aluminum dome tweeters in the Revel F208, you want something smoother that will be more forgiving of those bright tweeters.
Kell showcase or anthem avm50
