I don’t like the sound of those paper mids and woofers, to me they color the sound way too much, If you drive the kappas with a capable amp, Krell, Pass Labs, Threshold should do the trick you will be rewarded with great sound, I have also used tubes on the top of the kappas and a ss amp on the bottom woofers with no problems and it sounded incredible, as for the Renaissance speakers...they are in another league, it wouldn’t even be close, I’D put the Rens up against any 10K new speaker, they are that good, I have the infinity epsilons and I have searched for new speakers to best them but You would have to spend upwards of 40K to do it, believe me I searched.

I have no argument that the Kappa's are nice speakers and can be incredible with the right amplification, but have to assume from your response that you don't like the sound of those paper mids that you haven't heard them. 
The paper on these mids are coated,  next, the problem that most people have with paper is how you can hear paper resonate,  some love this, others don't.  The slits in the cone, stop the resonating from spreading and moving around the cone,  then the slits are glued with a pliable material that further dampen the cone. (paper is normally more detailed sounding than poly - not always) 
Lastly, with proper crossover changes,  I really like the Kappa 8 & 9 both, many of their issues can be solved, but no matter what, these speakers have aged and the poly domes are shot and all Kappa woofers are ready for at least a recone.

Yea I am one of those people that don't like the sound paper cones.

Paper changes it's sound characteristics way to much for me, they absorb humidity when it's damp out slowing down the cone and making it less controlled,  they can also deform or warp from the humidity as they dry out.

 And then they are coated, so what happens in a few years when the coating hardens/drys out, the sound changes.

With all those slits and glues and special coating to stop the cone from resonating why didn't they just use a better material for the cones to solve the problem.

As for the polydomes you can buy new replacement domes overseas, a guy makes them out of the same material as the originals, they look stock.
 Also a guy in the states is working on exact replacements.

 I have RSDS polydome replacements that I modified and A&B'd up against the original polydomes and the RSDS were much better sounding 

 I also have a pair of genesis titanium replacement polydomes should mine go bad, so I'm good.

 I have been treating my original polydomes once a year with silicone shock oil for the last ten years and mine are still like new.

I agree with you... if you like the sound of paper cones then they are for you, if not... there are so many other speakers out there to choose from.
