Summary: We bought one four years ago for about $1,450. Lights out on knobs, one burner wont ignite (electrical), and knobs show unusual wear for such modest use. And now the units are $1,900? Spare yourself.
Summary: I have owned this now for 3 years. Here is the what has happened. Within the first 3 months, the light on the knobs go out. Luckily under warranty so the circuit board gets replaced at no charge. Rest of the 1st year no problems. Second year, one of the back burners does not ignite and I am using a lighter to light that burner. Also the large burner and next largest burner keep clicking to light even when the burner is lit...extremely annoying.
Summary: We had our cooktop installed 2 months ago. So far we love it. Our install was on an island where we couldn't have a hood. So the one "ding" I would give Dacor is that the power burner should have been closer to the rear (or be the center burner like it is on the 1 level down version) so that it would be closer to the rear "snorkel" ventilation (ie. the ventilation wall that rises up).
Summary: I tried 3 times to order this cooktop in the 30" model. I believed it was a high end cooktop with nice features and American made (I would like to buy American whenever I can). The first order took 4 weeks for the manufacturer to send it as it was on back order. It arrived with several sides containing dents. The box it was delivered in was fine so it was not damaged during shipping.
