Dura-Son or other sound underlayment experience

I want to do a floating installation of an engineered hardwood floor on a cement slab.

Does anyone have any experiene with the Dura-Son product www.dura-son.com.

I am looking for optimum sound deadening performance.

I've never seen this stuff so I checked out the site you provided. The thing that leaped out at me was the "enhances underfoot comfort" statement. That tells me the stuff is probably padded too much. Remember the only legitimate function of pad under a floating floor, be it laminate or engineered wood. It's there to deaden sound. If it's too padded, the joints where the planks come together will "work" too much, will self destruct over time, and the floor will fail. It's kinda like bending sheet metal. Take a piece of sheet metal, fold it in half, and crease it. If you want to break it, flex or "work" it dramatically and it will break readily. If you just flex it, it will last indefinitely. Floating floors don't like flex. That's the reason for the flatness requirements. Too much pad, too much flex. I would advise caution.
