Why are my SF Venere S Speakers not sounding as warm?

I have a beautiful pair of Walnut Sonus Faber Venere S speakers and I use them for everyday surround sound/music listening in our living room.  The issue is I fell in love with these speakers in the showroom, and when I set them up in my living room they sounded almost piercingly bright and not nearly as balanced and pleasant.  I have bi amped them with my Marantz SR 6012 Surround Receiver, ran the room EQ set up as well as tried to manually EQ the system.  I was able to take some of the brightness out and get them to a more balanced sound.  I am VERY happy at the un-hindered sound quality they produce.  However there is not near as much bass as there seemed to be in the showroom (I had them disconnect the separate sub).  Now I understand my room is not treated and that of course makes a difference.  I added a Definitive Technology SuperCube 2000 and that has helped, surprising amount of bass for such a small discreet sub.  What are your suggestions?  What am I missing on the set up of these speakers to get the full range from them?

We have a tile floor and a raised ceiling that is at an angle from approx 9' up to 15'.  We have a large fabric couch with an area rug and wooden coffee table.  The dimensions of the room are approximately 14' deep and 19' wide.
