Upgrade path?

I’m getting close to the sound quality I desire, but I’m now wondering about the path I took to get here. Is there a right or wrong upgrade path? Maybe carving the path as you go is the best way? I don’t know and I’m wondering what worked best for others. 
I finally have the gear I lusted after, but never considered upgrading the tubes in my amp or adding room treatments until now. Assuming you already have a decent room, good gear, proper speaker setup and dedicated lines and good cables etc, where should tubes and room treatment fit? If room, amp and speakers are #1,2,3, what importance or number should be assigned to upgrading tubes and room treatment?This whole time I have been working towards my ideal “3D” wide soundstage that will go outside of the side walls and past the front wall with great imaging. It’s getting there and I’m hoping by changing stock amp tubes to some NOS tubes and adding room treatment will get me to my “happy place.” Amplifier is a Line Magnetic 805ia with all the original tubes. I have just invested in several NOS 6SN7 and 6SL7 tubes (arriving next week) and torn between GIK and Acoustic Fields for room treatment. Will these tubes make a huge difference? Will room treatment make a huge difference? What has the most affect in order?
I know there are a lot of questions here.


@ veerossi, Room treatment huge difference. Acoustic fields is great.  :-)
Yes look at all my YT vids,, there you will see all my upgrades in amplifier etc. 
NOS 6sn's is a  nice upgrade
let see I know that amp well, but since surgery can't quite recall, be right back.....

I am pushpull fan,,,

Treatment probably the biggest difference. No guesses about the tubes, they are all different from each other.
Is there a right or wrong upgrade path?

No. Only wrong path is to buy stuff that doesn't sound good.
Room. If room is treated well, you will hear the subtle differences when you roll tubes distinctly.

Veerossi, Room treatment will have much more of an effect than the tubes if done properly. It is easy to make things worse.
The single most important element here is the speakers. Many are incapable of doing what you want. Pairing them with the right amp is next. Room treatment third. The type of treatment you use depends entirely on the speakers given a specific room. Everything else is relatively minor unless you listen to vinyl then the Tonearm/cartridge combination takes precedence.
Thanks for the advice so far. I am planning on the room treatment as the next step but also managed to try different NOS tubes. Wow, it did really opened up the sound a lot. Im looking forward to getting the room issues sorted to really maximize the full potential of the rest of the gear. I’m looking forward to getting back to enjoying the music and being happy with the quality of the sound. As fun as it is to constantly tweak annd adjust, there are times where I just want to relax and enjoy the music.
