Help! Advice and Recommendations please (system sounds bad)

If one takes the time to look at his system and check the picture of his new "wood paneling", it is evident that it is much more than that. More like a bunch of wooden slats right next to eachother. Lots of wood. If it's made of pine, it is one of the most absorbant wood there is. 

Awesum system. Continueing with some advice here. Maybe break the rig down to basics. Can you run the streamer/dac directly into amps, or try a different source? Remove pre amp, crossovers, subs. Get as basic as you can. Check all interconnects. A digital volt/ohm meter can verify shorts/ opens. Check line voltage several times on outlet your using. Is there some high amp draw appliance on same circuit? 

Ive had troubleshooting finds such as loose interconnect, gain switch on phono pre set wrong, mono switch selected on pre amp. 

Curious what your culprit will be.

Is it possible that the mode switch in the crossover is in the 3-way position instead of the 2-way position?

Impressive system.  Should be wowing you regularly.  What are your cables?  Based on what you've spent so far I'm sure they are also top notch.  But they can be a "choke point" as it were, especially in a system like yours, even if they're good but are a mis-match.  Still, something isn't right.  I get room issues.  I live with room issues.  But even my system, which is way below yours, delivers clear and lively mids and lower mids, good separation and is very engaging musically.  I'm thinking maybe your crossover is set way too high.  I'd try turning the subs off all together.  Does some of that airyness your looking for show up?  If so, then listen without the subs for few days until your ears become accustomed to the sound and then ease the subs back in until they just barely touch the lower mids.  Listen for a while to again let your ears become accustomed before adding more.

The only other problem I could think is there is a hardware issue.  It'd be in either your pre-amp or crossover.  A tube that works but is actually failing, a weak cap or leaky diode somewhere.  Devilish to track down.  Maybe test with the crossover removed?  Can you swap in a different pre just to see what happens?  Even with a lousy listening space, your system should be singing.  Something's not right.

No one has mentioned the dropped down ceiling.  From my recollection dropped ceiling’s have a bad reputation for audio, way too absorptive.  They are likely more effective at reducing sound transfer between floors or reducing room noise for things like a pool table or other noise making activities within that space.  Also from your photos it appears the ceiling is a bit lower than your previous room.  Installing a drywall ceiling would likely be a major improvement.

Are you using the same listening chair?  Seating height can also alter your perception of the soundstage.
