I would agree with diegs on Aperion and Axiom.
I had a chance to audition the Monitor 7 as well as the Studio 20, 40 and 60 and then various axiom offerings.
Compared to the others, I found the studio 7 lacking. The bass was muddy (not well defined) and the midrange and high end were veiled. In comparison the Studio line and the Axiom offerings (M22, M60, M80) had a much more detailed rich sound all around.
The bottom end was much more textured. A plucked bass string sounded like a plucked bass string rather than a bass note. Vocals gained a 'right-there' sound. Not just more detailed, but also much more real.
I did not do a side by side comparison of the Studio line to Axioms offerings so I cannot say they sound the same, but they sure are close and at the price of the Monitor line.
I have seen one direct comparison between Aperion's T6 (I think) tower and the Axiom M80 and the two were very similar in sound.
The catch with Axiom and Aperion is that you need to find a person that will let you audition them, or try them in your home.
