What kind of amplification do you use? Alex F was nice enough to answer some of my questions, but I'd like everyone's opinion. How much juice do the LSi9's (or any model of the line) need to really make them sing. If I get the 15's I would buy another amp just for them, so for now I just have to worry about the 9's, center, and two rears (energy eXL15's for the moment). Here's what I have been looking at: $500 and below range Sherwood AM9080 120X5 Parasound 855a 85X5 $500-$1000 range Parasound 1205A 140X5 Adcom GFA 7400 100X5 Marantz MM-9000 150X5 NOTE: All those wattages are at 8 ohms, and the LSi series is rated at 4 ohms, but it actually averages 6 ohms (straight from Polks mouth). Not sure how that would "change" how much power the Polks would actually get.
