Agreed, it should work well. I have the far cheaper Sony HT-XT1, not sure if it's active or not. But it connects via HDMI and has Bluetooth. It works brilliantly for television, movies and music. I stand the television on top of it though. You couldn't do that with the Naim.
If I could convince my girlfriend, or reassure myself I would not be killed for doing so, I would buy the Naim for this same purpose.
