Infinity Kappa 8's


What to do? My infinity Kappa 8's keeps eating amps for lunch.The 1st failure was with a Yamaha 200 watt per channel model P2200. Amp went black, I replaced the main fuses on the back of amp, it powered-up with new same rating fuses and then amp died again for good.Tryed another P2200 fuse blew again. I've decided not to try the amp again, for fear of completely damaging my last P2200. This is getting expensive! I'm not cranking the volume at full tilt or pushing the bass tone control past 12 o'clock. The speaker can be Bi-amped, but I've just used a single robust P2200 on them. The speaker wire uses large 1/4 inch bananna connectors, so no bare wires can not touch positive to ground on the back of the amp or speakers and the 4 binding posts on the speakers flat metal plates to connect the two binding posts together for single amp operation. Could a faulty cross-over wreak this havoc upon me. Any helpful suggestions will be greatly appreciated.

Having owned Infinity since the early 70's, and Kappa 9's were here for a while I can tell you what you need to do.
You won't like it but you need to step up to an amp capable of handling a 2 ohm load, one with high current capability. Me, I like levinson, on my current pair of RS1b's, I'm using a vintage ML3 levinson on the woofers, no problem.

I would suggest Classe, older Krell product, Levinson 333 or 336. Do not even think of anything under 200W/channel.

Step up to the plate and give the Kappas what they want. Until you do, you will continue to have problems.

Best,

Paul :-)

Sorry but a Krell, Levinsen and Classe at the power required is just outside of my budget.

There are a few Classe 200/201's listed around the $1200 range. IMHO that's reasonably short $$$ to get the job done right. The Yammie is a good amp, however it just ain't got enough when the impedance dips. That P2200 is about to celebrate it's 30th birthday, maybe it's time to put the old girl out to pasture ;-)

Good luck,

Paul :-)
