Sound meter + equalizer = problem solved?

Digital room correction is like a spare tire, hopefully you never have to use it.

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.

Equalization changes the speakers input into the listening space; room treatments change the output of the room to the listeners ears. They are both useful but totally different tools. Every time you move a speaker, schangecthe toe-in, raise them up  or down, you are changing their input into the room. It is every bit as much equalization as turning a knob, with the added complexity of changing the speakers acoustical interaction interactions with the space. Equalization cannot fix a bad room, ever. That requires acoustical treatment. 

I have EQ for my system (a Schiit Loki is there but not hooked up unless something really needs it) and rarely use it as all I generally need to (rarely) do is adjust my subs...my large, untreated room sounds great as it has furniture lots of crap in it. I guess I know from decades of experience how to set things up to suit my tastes, so there's no problem to solve.

I would change 'Sound Meter' to 'Personal Preference'. It does not matter how it measures, it matters how it sounds. A flat frequency response not necessarily is the perfect response for everyone, or for every music genre.
