i watched your video, nice gears having separate setup for music and movies, four floorstanding branded speakers,separate amp and receiver, with subwoofer- this is already a pricey setup.
maybe you can add a little sound isolation/sound proofing materials for reflective surfaces for a better audio. i noticed that you have a very limited space for the cluttered gears, maybe the reason why you settled for a small led tv.
your video is comprehensive, precise and humble down to earth with its title as poorman's setup. (i realized i am poorer than you...)
and you have a nice voice too, you can be a good DJ.
