Not perfect circumstances, but I heard the QLN top of the line and Borreson’s at AXPONA. I fell in love with the QLN’s and want to demo a pair, thought I think I could only handle the 1’s in my space. My impression of the Borreson speakers was similar to @avanti1960 , way too tight. I am sure that could be dialed down with the right gear, but not my cup of tea.
