I currently have a 5.1 JBL setup consisting of the JBL S Center I, 4 JBL S36 II's, and a 10" JBL PB10. I love it - no complaints. But now I have a wonderful oppurtunity. I can get my hands on either the Klipsch Synergy series speakers or the Athena Audition series speakers for half their retail price! That of course narrows my upgrade options down to JUST these two brands and series'. Not that I'm complaining. In any event, I'm looking at one of two packages. Either the Klipsch Synergy SC-1 center, 2 SF-2 fronts, 2 SS-1 surrounds, and the KSW-12 subwoofer. Or... The Athena Audition AS-C1 center, 2 AS-F2 fronts, 2 AS-B2 surrounds, and the AS-P400 10" subwoofer. With either one I can eventually also get an additional set of bookshelves for rear 6.1 or 7.1 channels. So, my questions... What do you guys think of these two series' of speakers? Why would you recommend one over the other? How much of an upgrade from the JBLs is this, if any? I don't know what further info you might need, but I'm using a Yamaha HTR-5560 6.1 receiver and mostly watch movies, though occasional game playing goes on. Thanks in advance.
