Guy's your wearing me down I'll say it again.
Start with a room that has been treated acoustically otherwise
you'll be chasing your tail.
I assume since the OP didn't mention any that he's still
dealing with whatever is going on there.
Once treated as far as you care to implement, then start
with gear changes.
Both rooms I've used for music were substantially improved
and allowed me to differentiate between how the room sounds
versus the gear.
It took me awhile to become a room treatment prognosticator
but I wish it had occurred much earlier in my journey.
Great gear in a so so room will still be so so unfortunately.
