I have heard an older set of the Kappa’s; it is a friend of my brothers that has them. The Infinites have a more bloated bass, too much for my tastes. The mids and highs were not up to par with the Axioms either, in that they just didn't reproduce either as clear. The Infinities did play pretty loud but no where as clear at the same levels as the M80s are capable of. So I would think you would hear quite a difference between the two. Will you like the difference, I couldn't say. You hearing them yourself is the only way to see. If it were me I would take BrotherBob up on his offer and go check them out.
