I'm looking for opinions. I use my system for both movie watching in 7.1 surround and for listening to 2-channel music. I'm currently using a Yamaha RX-V2500 Receiver, it's getting old but it still sounds great! My front speakers are Zu Audio Omen Standards, Zu Audio Omen Center, Zu Audio Undertone Sub and my surrounds are Tivoli Design TDHT1's. I'm thinking about purchasing an Emotiva XPA-3 Amp to drive my Zu fronts and center and continue using my RX-V2500 to drive my surrounds. Any thoughts on this?
