Your room is your final sound. Do all the tweaks you want, buy the best gear, and if your room is not treated it is a waste of money to getting the sound what you paid for. I can remove just one panel that sits between my speakers and the sound dramatically changes. Same on taking off the bass traps in each corner the same, heck even tilting my blinds upward but not closed or downward not closed changes the sound. It really is something when you try to make a good-sounding room, how so many little things can make an impact on your system's performance. This is why a review on gear or what you hear at a local audio store if you are luckly enough to have one means little, only when you get that product home in your system can you tell how it will sound and work in your system. The room matters so much.
