Room treatments for a lively sounding room

I recently remodelled my 10 x 15 listening room as well as the adjacent room it is open to. New paint and hardwood floors now instead of carpet. The room sounded to "shouty in the midrange".  I bought a large area rug for the room but the room was still too "lively" sounding. Tried putting a blanket on the side wall not adjacent to the open room.  Sounded much better, but unattractive. So just I installed a multi panel room treatment kit from Primacoustic last night. I was just curious what other members of this forum have used and what  room treatment experiences have worked best for them.
