amp for infiinity kappa 9

Glad to hear that you've finally found an amp that will tame those beasts. I would suggest looking into your preamp next in terms of upgrades. Most of the mass produced SS preamps that i've heard have a very characteristic sound to them and it isn't very pleasant to listen to over an extended period of time. Going to something that is a little more refined in this area will probably get you a lot closer to what you are looking for without removing the "punch" that you've got now. Sean

After reading a lot of the responses to your question, you might be better off just selling them. Sounds like they are more trouble than they are worth. Of course, that's just my opinion, since you have to live with the choice.
In any event, good luck.

Yes, as others have said, most Infinity speakers are VERY power hungry and the Kappa 9's are no exception plus getting parts for the older speakers can be tough. I have owned a pair of Renaissance 90's for the last 10 years and was driving them with a Threshold S350e 150 wpc and it handled them ok BUT they could have easily used TWICE that power to sound their best. I have since sold my Infinitys and bought a pair of JM Lab 946 Electra's and they are FAR superior to the 90's in every way. There is definately something to be said for efficient speakers.

I hope you got a really big amp by now.
Sorry to tell you this, but even your first amps hould have been able to drive those without frying. (Not nicely and not easily.)
Your 800 ebay deals most likley have a bad coil or perhap a few fried resistors. Better get all that checked first.
Or perhaps by now you are just disipating more heat into the cabinet.

The speakers have been tamed by the aragons. I don't think there is any damage to the speakers. They truly are that difficult to drive. The man I bought these speakers from was an older guy who couldn't have wooped on them. I know this because He was using a 200 WPC Mcintosh, don't remember the model but asked if I wanted to buy it a month ago. He also had the foam surrouds replaced just before selling them to me. This is also true because those woofers are so stiff it takes alot to get them moving. With all that being said I have to agree with most of you I should sell them because they are not the greatest sounding speaker that I have ever come across. They are however the best sounding speaker that I have owned personally. The mids and tweets are great especially with female vocals. I really can't fault the speakers or the amps just yet as they are not in an ideal envierment. The amps will need a dedicated circuit as Sean Has stated before. The room is also less then disirable. Its to small and has no treatments and I really need to get a better pre amp. All this will be addressed this summer when I rebuilld my family room. I might even do something real stupid and go for a HT in that room. At that point I will most likely have to move this thread over to the HT section for the advice of them guru's. I must say I have learned alot here in a short time and thank everyone for the great pointers. When I get my room finished I will better be able to determin If the big Kappas should stay or go. As for now I just hope that the newly refoamed woofers loosen up or a sub is going to be a must.
