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?

You probly already know this, but thier is a current limiting switch on the back of you speakers just to the right of the crossover. It's under a black plastic cap, with this switch put to the normal position that parasound should never have any trouble. It is a very durable amp. Even switched to extended it should be able to handle most music. I had a pair of kappa 9's years ago and found that I had to biamp them to get the sound out of them that they are capible of. I has one Bryston 4Bst on them first and had your problems but found positioning was very important, I played with them for a few nights to get them to sound powerful and smooth. Then i bought a second 4Bst and ran then in extended mode and they where incredible. I found they should be for best sound 10-15 feet apart, the distance between the speakers and the primary listing area should be slightly greater than the distance between the speakers. To obtain the lower coloration and excellent stereo imaging position them at least 2-3 feet from walls and corners, if the bass is a bit light under these conditions, move the speakers slightly closer to one of these boundaries. Moving the the seating position by as little as 6-12 inches forward or back can result in a large diff in bass energy. positiong is very important on these speakers, if not positiond wright they won't have any bass and sound bright and harsh.
I sold the kappa's and now have Infinity 1b's. the brystons could not handle any amounts of volume so I now have Krell and Conrad Jhonson mono blocks. I also spent many nights playing with positioning again, but once you find that sweet spot they are incredible speakers.
