I beg to differ about Underwriters Laboratories (the "UL" mark on a product). As an engineer working in both consumer and telecommunications areas, UL is concerned with components on the circuit board along with both power and any network connections. If you look at the individual components, you will often see a UL Recognized mark for the manufacturer in the datasheet of the individual PCB components along with the flammability rating of the plastic used in its composition.
The circuit board itself is usually FR-4 material or similar. Due to increased product safety laws regulatory agencies throughout the world are most concerned with the materials used in the product construction. The next time you purchase a computer, tv, etc. note UL, CSA, CE, RoHS, WEEE etc. approvals in the documentation, and on the serial number label of the unit. Note all of the safety warnings in the product manual as well.
The UL File # E175216, is assigned to Funai Electric Co LTD as per the attached. As the Denon Blu-Ray models are listed, I expect the file to be updated to add the Marantz BD8002. There are 4 E175216 listings at UL's directory, and I am sure they will be constantly updated. Many companies assign the UL File to the contract manufacturer who actually builds the unit, others have it assigned to the designer or the company who markets the unit.
The file number means that the listed device meets the appropriate UL criteria at the time and is given the right to attach the UL Listed or Approved label on the product for product liability reasons.
The point of my earlier post was just to point out that the Denon and Marantz units will probably be very similar electrically as they both will be built by Funai. Note the back of the Marantz unit. Compare it to the Denon.

I will purchase either a DVD-3800BDCI or a BD8002 when complete documentation is available on both units. This is in no way a putdown of Denon, Marantz, or D & M. I have both brands in my system and find their quality, specifications, and features superb. I was just making an observation on available documentation on both units and will continue to be a customer of both brands.
