I recently bought a Klipsch Synergy surround sound setup (B-3, C-2, S-2 and Sub10). I originally was using a Yamaha RX-V663 receiver and was not impressed with the sound, it was very bright and had almost no bass. I went through almost every setting and could not get the sound I wanted. I've heard theses speakers hooked up to a low end Onkyo receiver and sounded great, so I'm not sure whats going on.But anyways now Im looking into getting a different receiver. I've been looking at the Onkyo TX-SR607 but I am not sure....Any advise on what receiver would pair well with these speakers?
