I know this is subjective and I should get a pair of each and test for myself but I want to know your opinions for those that have heard both under similar variables (similar receiver, etc..) The problem is I went and heard the IL10 at Soundtrack today and was suprised at how well they sounded. I then went to try to hear the s38 at best buy but they were not hooked up and I was short on time and had to go before help arived. I just dont know if the jbl's will get a fair audition in the noisy best buy audio rooms compared to the dead silent soundtrack room. How can I make a fair assessment when variables are not the same? Tomorow I will go to a different best buy and hopefully try them, but until then which has the overall better sound in your opinion for those that have heard both in a fair matchup? These will be used in a full 5.1 setup for 1/2 music listening and 1/2 dvd and movies. And obviously I want to match them so I will get all one brand or the other. Whichever set I get I will pair with a svs sub.
