Kappa 9. Parasound HCA-3500 WILL NOT power them


I purchased a pair of Infinity Kappa 9's a few weeks ago. I had the Infinity RS3A's and decided to sell them and upgrade to the Kappa's. I first hooked them to one of my Denon POA-2400 200wpc amps. Not enough power. So posted this problem on here and after some research I decided on the Parasound HCA-3500 350wpc dual mono amp. So I bought one from a real nice guy here on audiogon. I hooked it up last night and this thing won't power them! The amp gets real hot fast. It clips when turned up and the speakers sound like crap. We hooked up a pair of Infinity SM-152's to a Denon POA-1500 150wpc amp next to all this and it sounds better! Also, I think I blew one of the soft poly mid-ranges. The yellowish white rubber on the mids turned clear around the outter edges after listening to moderatly loud music. I'm really frusterated. Three thousand dollars later my stereo sounds way worse and I can't turn it up as loud as I used to. Does anyone have any advise? Could there be a short in the speakers? Why did my midrange blow? What amp should I buy now?

Actually the Kappa's are know to dip under 1ohms, and if I remember correctly Threshold, Krell, etc or any other Apogee style amp ( you could look at the H20 digital amps that apogee owners get) Adcom 565's were modified to remove the protection circuitry so they could dip under one 1ohms but sometimes they would fry.

I hope you have the amp out in the open? Don't put that Parasound in a rack and run it on your speakers it will thermal for sure.

a sub 1ohm load is a short technically that's why your amps will heat up so much, and when they run out of juice they send crap directly from the wall to your speakers and cook drivers.

If you want to rock you will need a serious amp that can play at 1ohm. Not many amps will do that, look for 1ohm rating on amps.
There is definitely something wrong with the crossover or one or more of the drivers is shorted. More power will not solve your problem. You need a knowledgeable tech to examine them. Do not buy another amp. Danger Will Robinson
The midrange might not be blown. The domes clear up after being heated. In fact, if you CAREFULLY use a hair dryer on them, the yellow will disappear. I think I origionally recommended a pair of Carver Pro 1600's and I'll stick to that.

You're singing a song I've heard before.
Music Reference RM-200 handles loads down to 2 Ohms.A 1 ohm dip ask Rodger at Ram Labs/Music Reference.I've heard these speakers before with a Vintage HK Citation II Tube Amp that puts out 60 watts per side.JD
