If you have a nice system why do you really need room treatments?

The point of the entire thread was to better understand whether there's a benefit in doing room treatments given a furnished room which already inherently does a lot of this. 

@emergingsoul  Did you investigate any of the sources of technical information offered?  If so, your question posed should have been answered long ago.  I see no indication you have anything but opinion to offer that is based on your room as a single example.  I see no indication you are open to better understand.

Have you listened in rooms you consider excessively treated?  Do you have actual measurements to present of untreated, treated, or your room before and after?

And for those who still feel inclined to put acoustical treatments in a furnished room I'm not sure it would really be helpful and actually maybe harmful.

Proof???

I hardly feel that corner bass traps and very modest absorption panels in a furnished room is a serious effort to acoustically treat the room.

It may not be but it’s still treatment as well as your rug.  You treat the issues you have in the room and not every room requires the same level of treatment.  A lot of your responses as well as the thread title make it sound like you think if the system is good then it shouldn’t need treatment in any room, only to find out you have treated your room to manage issues you have.  You can over treat/dampen a room for sure but I’m not sure most folks on this site are doing that.  They are doing just enough to sort out issues.  I guess it’s just between your thread title and opening comment that you make no mention of any treatment then it turns out you have some and have done some measuring (I think both of those things are good to do).  That’s what made it seem like you’re all over the place.  

Oh, and you both hate bookshelves but wish you had them.  I’m not judging you just making some observations that make the point of the thread hard to follow.  By they way, how do you like your 901s?

Somehow I think if you have a good system in a furnished room somehow you have to validate yourself as a true audio connoisseur by putting stylish acoustical panels throughout the room. Somehow not having them makes a room seem unfinished even though it may sound perfectly fine. I think people are hooked on getting acoustical panels in their furnished rooms and may just live with them after they get them because removing them is something they probably just wouldn’t do. A diffuser panel of 3 x 5 in a furnished room room hardly does much of anything, but it can look really really cool. I would have one but I’ve never found anything that I’ve really want to put up on the wall.

I think everyone’s been conditioned to assume they should pursue acoustical panels even though many can never really discern a difference in a room that’s furnished. . Walking into a room with a nice audio system without acoustical panels and someone will say oh you need acoustical treatment.
