Thing is what good would a meter do me? What is the point? That giant Sony box is like a furnace in there. Even when turned off it goes into a "standby" mode and still generates a lot of heat. When turned on, unless you leave to doors open if you reach inside and touch a device inside there it will almost burn your hand. I think I have the ROKU issue (sort of ) figured out. This system does not have quite the "punch" of that furnace, but it's so much less cluttered.
I may look for another bar type system and see what I can find before I fully commit and run the 2 wires needed under the floor and mount the 2 rear speakers on the wall.
I think some of what I am seeing is also my TV does not have EARC only ARC and I think there is some loss of functionality there.
But, I may still try to find a bar system with a "shorter" bar. As this LG one hangs over the cabinet about 3-4" on ea side. Little weird looking. But for now I LOVE the wireless aspect of the SUB and the receiver to the rear channels with only the 2 wires between the receiver and feeding the 2 speakers. So much less "clutter and fuss". I love that aesthetic
