Infinity Kappa 9's sound terrible...HELP

Recently I got a pair of Kappa 8's. Plugged them into Adcom 860 preamp and to an old HK Citation 16, GFA-555 and GFA-565's. They sounded...beyond my wildest dreams! Absolutely amazing!

A week later I bought a pair of Kappa 9's. Was really excited thinking they would out preform the k-8's! Plugged them into the same system and they sounded like crap. Tried running each k-9 to 1 GFA-565 and bi-wire them, changed all knobs to flat, experimented with the adjustments on the back of the k-9's in every conceivable position, ran them in standard and extended bass modes...and they still sounded terrible!

Has anyone experienced this before? Any tests or checks I can do to eliminate any doubts of anything? If I can't resolve this on my own, I guess I'll have to take the speakers somewhere...if I can a reliable source between the Philadelphia to Harrisburg, PA area.

Also, if any can suggest any good techs between the Phila and Harrisburg area for amplifier rebuilds (Adcom GFA-555 II models) I would also appreciate getting a name and address.

Thanks guys...appreciate your help!

Please explain what is wrong with the sound so we can advise. No highs? Loud scratchy noise? No bass? Just not to your liking or terribly distorted?

Did you sell the Kappa 8's yet...? I mean, why pull your hair out trying to get the 9s to sound good in your room if you like the Kappa 8s better?

Call Bill at Millersound just outside of Philly (215-412-7700). He is THE MAN when it comes to Infinity speakers.
He will make yours sound better than the original.
Tell him Vinh Vu sent you.
Good luck.

If they are the 9.1 series 2, I have heard that they draw some serious low ohm loads. If your amp cannnot handle the draw that could add some strain on the system. There are a couple of Infinity Classics groups that have some good information available & some knowledgeable folks.
Here is one link; http://www.infinity-classics.de/infinity/index.htm
The one above is in German, but there is a english forum as well.
The other site is on Yahoo in their forums group.
Good luck, John

Surprised the 8's sound that good with adcoms in the first place.. so obviously you found a rare match that works that smoothly with adcom amps and I would leave it that way.. however you will probably need far better amps for the 9's unless there is just something wrong with them. If keeping the 9's I would look at selling the adcom gear and getting a vintage or newer Mcintosh amp, should be no problems then.
