I have a recording studio and when starting out an acoustically treated room is the first issue to solve. You can be using the best mics in the world, the best mic pres and speakers and it’s pretty much all irrelevant and a waste of money without first treating the room.
If you want to know what the mixing and mastering engineer were hearing and intended in any recording, then your room must be treated.
On the other hand, I’ve met people who listen to music who don’t care about that and actually prefer plenty of close reflections and reverb in the listening environement.
But one thing is for certain: all the money spent on expensive equipment is, in many cases, a waste without addressing the room because you’re not hearing the equipment nearly as much as the sound of what it’s sitting in.
