omegalau, you keep saying you just came hear to find out the reason these differences exist...
You've been given the reason. You're just not willing to accept it.
Most of these differences you hear are imagined, which is not only a normal but an extremely common thing. As far as the science behind digital audio goes, that's all there is to it. If you want some bizarre theories that support all of your claims this isn't the place to find them. Maybe try the cables and tweaks section, or just keep asking your friends.
