I currently have the KSF-8.5s as mains and I've heard great things about the KSF-C5 center channel and the KSF-S5 surrounds, which are matched with my mains, but, I can't really find them anywhere and I don't want to go through ebay or any auctions. So, I heard the reference 3 series is the closest match. I have seen the RC-3 center for about $250 and the RS-3 surrounds for about $500. How do these speakers match up to the discontinued synergy speakers previously mentioned?
