Yes it’s always better to not do a lot of things if not needed, like take prescription medicines, but if it’s needed then it’s needed because the results are better than the alternative.
I like a simple audio path as much as the next guy if that’s all that’s needed but that alone won’t cut it if the room acoustics are sub optimal. You might be able to fix the acoustics relatively easily in some cases but not in others. The point is there is that one extra option available that can help and is very easy and practical to apply….equalization and maybe even digital room correction. I am considering that perhaps as a good way to make my lesser room sound more like my good ones.
