I have the Energy Take Classic 5.1 connected to a Denon 791 AV receiver. I have been happy with both so far. Is it worth upgrading the speakers to Definitive Technology ProCinema 800? Or will the money be better spent on another receiver? I am only interested in sound, the rest of the features like number of hdmi, AirPlay, etc. are not relevant. My budget is around $1000. Thanks
