amplifiers for Kappa 9's

I challenged statements made in a Berning based thread where both David Berning and one of his cohorts responded. After a series of exchanges that built upon the foundations of where we were all coming from, i asked further questions / made further statements pertaining to the Berning amps and how they would interact with various loudspeaker loads. For some reason, those questions went unanswered even though the other parties continued to post in that thread. Somehow, the points that they couldn't refute or explain were conveniently overlooked.

As to bringing a Ford to a Chevy dealership, etc... Curl has designed gear for dozens upon dozens of manufacturers. Believe me, from his point of view, a design or circuitry that is new to him is a chance to learn about something that he may not be familiar with. Nothing more, nothing less.

As to high frequency artifacts not affecting what we hear, this isn't completely true. High frequency response above the audible band can directly alter in-band response in the ways of transient response, phase shifts, various types of distortion, etc... This is why i've said that spec's ARE important, but you have to look at ALL the spec's and be able to interpret them effectively. Looking at a few individual spec's here and there can be phenomenally misleading, good or bad. Sean

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

Gmood, I do not dispute your info on the Carvers, but then, why isn't there a Kappa 9 owner out there that is driving these ampeaters with the latest holy grail in audio amplification? I trust that these owners have been experimenting with older SS behemots as most Kappa 9 owners will try. I personally do not believe that I would ever try to let them run fullrange with an amp like the Carver Pro.

One word on caution: play with underbuilt amplifiers and the Kappa 9 and you are risking massive failure of either the amp or the Kappas, I would not risk the Kappas with inadequate amplification.

Remember another word: dedicated power supplies!

The last time I remember running the Kappas, it really juiced up the electricity of my outlets....could even see the lights pulsating with the volume going up and down.

hehehehe.

Kjak67, I just went through the same thing that you are now going thru. Seems like all the same posters are still here. AS a ownwer of a set of Kappa 9s I can say that Bemopti 123 knows what he is talking about. The Aragon 8008 or palladium amps are a good way to go for sure. There are no speakers out there that these Aragons will not drive (END OF CONVERSATION) I'm not saying that the Carver amps will not do the job I'm just saying you need to look no further then the Aragons that are availible right here on the "gon" for 3K a pair brand new. I would like to try Mitch4ts idea of Bi-amping these speakers but right now I don't have enough A.C. power in my room for addtional amps. This summer I will be remodeling my house and I will pull more circuits and give it a try.
