Unlike the devices of the HT-E Series this system is no longer compatible with the Samsung SWA-5000, ie you can not connect wirelessly to the system, the two Rear Speaker and must instead might an annoying cabling across the room in Mergers & Acquisitions. The included Rear cables are "only" 10 meters long, which (depending on the design of the living room) may be too little quite.
For the Blu-ray player, however, recognizes external hard drives larger than 2TB! I even use a 3TB hard drive, to which can be accessed easily. That can not be the most smart TVs (also from Samsung).
