Ah, but how many people fall for the DT Bullsh!t? A lot.
At least they don't seem to be lying about the new Demand series the way they lie about their subs and the BP series.
As for protection for the consumer? None, really. Except training your ears, and only trusting in good third party measurements to tell the story. I thought their BP series were some of the worst speakers I heard. I also had a DT salesperson warn me off their subs. Needless to say, I haven't been a fan.
That said, I do hope I get to hear the Demands sometime!
