For testing, I just watched King Kong and the scene where dinosaurs are running and escaping. My God .... I sounds amazing. Absolutely stunning. I can hear every bit of details Replacing the center peace with a tower and having all front speakers matching made a very good difference. The dialogs are crystal clear. Bass is absolutely mind blowing. From low bass to high has a very smooth transaction. Watching that scene was very over whelming. Having surround mounted 3 feet behind and I can hear even the mosquitoes flying around. I'm totally satisfied. Now I can call my sound system an impressive one.
