Hey, you mind your language, young man!
I don't own any DefTech now, but I used to own the BP7000SC. And I can honestly and wholeheartedly tell you that they sounded better than the B&W 800D, which I auditioned twice, 1 year apart @ 2 different locations. They also sounded 100 times better than the Paradigm Studio 100 towers. Wholeheartedly. Honestly. Cross my heart too.
