I currently have a marantz sr6010 avr. I will be adding a pair of RF 7 ii's. I will currently be using a 2 ch stereo system mainly for music but will upgrading to a 5.1 in the near future. My question is if I were to add an emotiva xpa-2 how well would this drive the speakers, and also can I set it up to watch tv through the 2 ch system for now using the marantz and emotiva? Any advice is appreciated. Thanks.
