Infinity kappa 9 or kappa 9.2?


I tend to like the driver complement of the original kappa 9 because it is what I am most familiar with, but I have heard at least two people claim that the 9.2 is a better sounding speaker. I have even considered the Kappa 8's to avoid all of the potential problems. I hope to drive these speakers (9's) with two Parasound HCA-1500's, but then hear one person who had trouble with even an HCA-3500 which specs with 8,4, and 2 ohm ratings from the factory.
Any help here would be much appreciated before adding another large set of speakers that are sometimes hard to re-sell. For whatever it is worth one parasound hca-1500 does just fine at high volume for extended periods of time on my current pair of Infinity RS-IIIa's. Many thanks in advance.

I have a couple of Infinity Renaissance 90, I just bought Jeff Rowland's Capri + monoblocs 501 ... this is an amazing transformation ! ...( I had before OCM 200 + Threshold Fet nine E)

crazy sound staging / imaging ... I can see the player in front of me in the room, how tall the singer is, a lot of space beetween the musicians

I open the full power on the Capri ... it becomes very (too) loud but without distortion and never hard

just great

this said, the idea of the Genesis 5 is a good one ... it depends on what kind of music you hear

good luck
I have the kappa9 before i use a hca-3500 to drive them, but they aren't enough power, the amp keep cliping when deep bass was playing, so i switch to krell ksa-300, the ksa-300 is very easy to drive this kappa9. it even burn the coil in the cossover. so i just upgrade the cossover, i replace all the coil that was burn, and all the cap to solen cap. right now they sounds even more liquid. on my opinion, i think the 9 is better than the 9.2 if you have the power to feed them, the 9 sounds more detail and bass is more quick and slam. but the disadvantage of the kappa9 is the vocal isn't warn enough.
The Genesis 5 isn't better in terms of preformance than the Kappa 9 if you power them properly.

The design is different, but the ribbon tweeters have the same low mass.

I would recommend you get a pair of Kappa 9 built them up new and you will be amazed how this loudspeaker can sound.
