Ok it's been close to three weeks now and I love the BICs more than my def techs. They are still breaking in and sound better and better everyday. I had to adjust the PEQ settings for each channel since the settings of the def techs did not work well them. Biggest thing I noticed was the clarity of the speakers, and tiniest sounds that can be heard when watching a movie that I didn't notice with defs. The bass is good on the fh66b when listening to two channel with sub off. When watching Deadmou5 on Netflix at the time between 26-30min of live concert that was recorded, there is a breakdown during a track where there was no percussion, and cranked up the volume to 19 on my Yamaha and I almost couldn't hear myself talk when I made a comment, I felt like I was at club in Chicago. It was AWSOME! Now waiting on pl66 to arrive on Monday, can't wait!
