I have to agree that the room is the most likely culprit. In time as you listen you may identify the room resonances that may be present. There is lots of material on this site about room treatment. There is a simple way to test the theory. Cover three walls of the room with blankets, duvets, drapes, carpeting, whatever you can lay your hands on. You will then be listening to your system without most of the room effects. Most find this quite an eye (ear) opening experience. Then you can plan more appropriate treatments to get the required effect.
My listening room has one wall naturally covered in curtains because it is all glass. Two more walls have curtain rails fitted along the top with curtains that are drawn into the corners normally. When I do serious listening I simply draw the additional curtains across the walls. The effect is amazing. The carpeting on the floor also helps.
