How do they sound to you? That's really all that matters. Def Tech gets the cheesburger rep b/c they offer so much for their price. When you look at the number of drivers, then factor in that many models come with built in subs you get a great bargain. There is a great deal of snobbishness amongst audiophiles, so bargains are often looked down upon. Ignore them, the real question you should ask yourself is are you a dipole person? I have mixed feelings about them. Some songs really benefit from the added soundstage and diffuse sound, while others are better off with the focus and detail of a direct radiator. I think Def Techs are much closer to Logans's and Magnapan's in they way they present music then conventional speakers. And they don't have the bass issues of the former two designs. How about Von Schweikert? There's another "Morton's" type name brand that will sound alot closer to your Def Tech's then a pair of B&W's ever will. Relax, have fun with your speakers, and decide for yourself if you like them.
