amplifiers for Kappa 9's


I have seen some feedback in here about the use of Bryston Amps for driving Infinity Kappa 9's, and agree that these are not the best amps to be using for these speakers. This is how my current system is set up, using 2 4B-NRB's, 10B Crossover and 12B Preamp... and MIT Cables throughout. I do find my Kappa 9's are very bright, but do not lag in the bottom end with the use of my Bryston amps. I am thinking about going to a tube amp for the top end, such as an Audio Research VS-110. I feel this will compliment my system quite nicely, however, any input or feedback about my idea would be appreciated.

Kjak67,

Sean was referring to me running Kappa 9's wirh a pair of Sunfire Signature amps in a vertical biamp setup. I also ran them with 4 Carver Silver 9t monoblocks. As far as I'm concerned, biamping them is the only way to go to get the most mileage out of those boys if you don't have a lot of money to spend on amps. The Sunfire Signature stereo amps can be had here on Agon for $1500 to $1800. The Carver Silver 9t monoblocks can be had for $1200 to $1500 per pair.

One pair of Carver monoblocks or one Sunfire Signature stereo amp will drive the Kappa 9's satisfactorally, however, biamp them and it's a different world.

The Sunfire amps were better all around from top to bottom, the bass was very good with the Sunfire amps, but could not duplicate the bass slam of the Carver monoblocks.

Whe I was running my Kappa 9's, I lived in a loft that was 22 x 70 ft with 20 ft ceilings. The Kappa 9's using the 4 Carver monoblocks or the two Sunfire amps filled the room with music to the brim with lots of headroom to spare.

I own two pair of Kappa 9's. I have lent one pair to a friend and the other pair is in storage. Hopefully, one day I'll own a room big enough again to let them stretch out and do their thing again with some serious high end amplification. My current room is 17 x 20 feet with 9 ft ceilings....the Kappa 9's were just too physically dominant in my current room and my wife wouldn't have it......so I am now biamping a pair of Infinity Rennaisance 90's with a pair of Sunfire Signature amps and life is good.

good luck in your quest
