My experience with a local Paradigm dealer before I bought my Ax's went something like this. After hearing several speakers from various companies, I had narrowed my choices down to three companies; Paradigm, Monitor Audio and Axiom(which I hadn't heard before). At first the Paradigm dealer was both helpfull and quite friendly but as I got closer to my decision and knew I was leaning towards the Axioms, he started dropping a few innuendos here and there...I guess he figured he had nothing to lose at that point. I did in fact, buy my Denon AVR, BD1800, and Paradigm DSP3400 off him at a very reasonable price, so I can't really complain(nor can he, for that matter).
I found other dealers to operate in somewhat similar fashion, if you mention another brand they'll usually start with "Well, they're ok, BUT..."
