Not sure it'll be helpful since it's subjective but; after restoring a set of four Kappa 9's I am of the opinion that a class D amp is the ONLY way to go with the 9's. Not that nothing else will drive them...just that you're needlessly burdening any traditional amp by doing so. If you like to turn them up...the loads both can and DO drop well below 1 ohm for extended periods of time. It's not this that kills the traditional amps...it's the resulting current draw and therefore power draw (power drawn goes up with the square of the current) that eats the amp. The class D options have become much more proven, available, and price favourable of late so check that out if you decide to go the 9 route...you will NOT be sorry that you did :-D Just my thoughts, Slug
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.
