This is getting blown out of proportion. While you can go all in to get the perfect room, there are still a lot of simple, cheap and effective ways to get decent sound, even in a typical rectangular room, which is what most people have. Play around with the positioning, height of the speakers, throw in a book rack and case in the corners and at the point where the first reflection is. If your room is carpeted then that's great, if not pick up a rug from IKEA for real cheap (the thicker the better, but still better than tiles and wood bouncing off). Make sure your stands are heavy - put weights on it, or use sand. All cheap.
Next time you go around looking for furniture, you can easily find specific designs that will integrate perfectly in to your room that will seem aesthetically and sonically pleasing. If you can't get different stuff, there are still multiple things you can accomplish by strategically relocating your current furniture. I guarantee it. I mean I see people spend thousands of dollars here on cables, dacs, amps, headphones and so on to get the best sound. I'm sure if people were interested enough in getting a rig right, they could play around with some basic positioning, furniture and carpets and still drastically improve the sound from before. It's genuinely not that hard to get decent sound if you put in a few hours planning and moving.
Also, now there's EQ and DSP room corrections that work quite effectively, taking phase and FR into account. You can get decent results with little to no spent money. All it requires is a bit of your time.
