Hey Guys, I have a 683 S2 with Yamaha RX-A1060. I am somehow not entirely satisfied with the music quality. Somehow only good recordings sound nice but not the normal CDs. Do you think I should plug in a pre-out Integrated Amp (Thinking of Rotel 1570 or 1592) or it it's just that the 683 S2s are not good for music? The Yamahas are rated at 110W 2 ch so it looks like there is some power there. I am not sure which way to go... speaker issue or just missing a good amp to see a significant improvement in audio quality. (P/S: I also have the SVS PB2000 as a sub). Thanks.
