I love the Def Tech's. I've had them for approx 20 months, and have nothing but positive comments. The Def Techs provide great imaging, and perform great on music and movies. I wasn't a fan of the built in sub concept, until I actually heard them. They sound amazing. If you are going for a music/theater speaker, I don't think you can beat them with even a greater priced speaker. If you are going for music only, I might consider something different like Dali, although I'm not so sure I wouldn't stick with the Def Tech's. Dali speakers sound wonderful on music. Regarding the fans, I'll let you know. As Riley804 observed in my comments, I've decided to go with the NAD. I guess I just needed reassurance for some crazy reason - Thanks Riley! I'll get back to you regarding the fans. I should have my NAD in a few days. Thanks for the feedback.
