Something just isn't there


I'm hoping some of you with experience can help me evaluate my system. It is, of course, hard to put words on sonic character but sometimes it just isn't there. My system is quite detailed and can have a very nice soundstage but rarely does it grab me. 

The system:Magnum Dynalab MD209 hybrid tube/SS amp,
Manley Chinook tube phono preamp,
Oracle Alexandria factory refurbished,
Oracle Prelude tonearm
Ortophon MC 20 super cart
Joseph Audio RM22si speakers
Audioquest Caldera speaker wire. 

As I have been upgrading the system, I'm left thinking that either speakers or room treatment need attention next.
My room is approximately 12x25with hardwood floor, hard surfaces including art and wooden furniture, two big sofas, and several doorways and windows.   My wife won't take kindly to funky acoustic treatments.Of course the speakers and cartridge are just plain old.  I find auditioning speakers daunting and worry that the showroom experience will not be representative of my home and my electronics. 
Any thoughts would be appreciated.

room treatment is the missing part of alot of sound not being up to snuff...went through it and thought i was doomed...1st refects and corner bass traps...speakers (behind) got the main mojo traps...simple...didnt have to do ceiling,ect.... lot of the times thought i needed new amp,new source...bs
Yesterday upon the stair, I met a man who was not there
He was not there again today
how I wish that man would go away!

In other words none of us can hear what you hear so we are just making gusses.
