System Help

Moved my system from 16 x 17 x 9 dedicated room to a dedicated 16 x 32 x 8 listening room. What once was a marvelous listening experience has turned into a diffuse, muffled, lifeless, boring system!

Speakers: Volent CL2i
Amps: ASL Cadenza
Pre: Allnic L1500 & Reference Line Preeminence 1A
2014 Mac Mini with Keces PS, SSD & maxed RAM

Any Suggestions? Can the room make that much of a difference?

Thanks
